On Breaks: Off the top of my head, there are only two bosses who you really benefit from Breaking: Sinspawn Gui (Power Break) and Defender X (Armor break). I think NEB's point is that Wakka's status on randoms is much more devastating since you fight more of them compared to bosses and the bosses that are vulnerable and where Breaking is efficient are so few and inbetween that the status just beat out the breaks.
Seymour Omnis is also someone breaks are worthwhile for, providing you aren't just going for "AEON SMASH", and don't have Celestials...and even if you do have Celestials, it still helps boost the damage of Magic as his Magic Defense is still significant enough, not to mention using Celestials on him = you gain no AP!!!!
Also, it is worth noting that Busters only last one turn, so Wakka has to constantly re-apply it, contrast to Breaks which last the entire fight. The Attack variants, which have less hit rate (though still generally adequate enough) last 3 turns; generally, Busters are only really useful if the enemy has absurd status defense such that the Attacks kind of fail, as otherwise you're constantly using MP to re-apply the status, though Wakka having Osmose makes it not as much of an issue as it could be, but just stating that just going "He has a Buster!" is not entirely remedying the scenario.
that said...
Final Fantasy 10:
Tidus: 7/10. Haste and Slow are good stuff, Cheer is as well when trying to squeeze out that Overkill, and I do recall him having more strength than Wakka until around Bevelle, which means he's killing wolves (or alternatively, Overkilling them when Wakka cannot.) Early Counterattack weapons don't hurt either.
Auron: 5/10. I'm somewhere in the middle, finding Auron decent enough at what he did, but nothing special at the same time. Though, I do want to note that anti-hyping him for Magic Defense is absurd; he has more than Wakka and Tidus, and he's got more than enough HP to make the lack of MDef trivial (he's one of the people who consistently survives Total Annihilation, for example), and since FF10 is NOT a game where MDef is a factor against hit rate...yeah.
Rikku: 6/10. Mix is good stuff, Use is good too, though that's really easy for Kimhari to steal the niche of cause, speed aside, its stat independent, and one of her EARLIER skills. Gets half a point for having actual usability underwater!
Wakka: 7.5/10. Yeah, Status is just too good to ignore (I was mostly slamming the oversimplification of the scenario, not so much the status itself), the accuracy cannot be easily replicated and Attack Reels hurts.
Lulu: 6/10. Nice Powerhouse and good for slaughtering Flans, but not much beyond that. The fact that its possible to make Yuna more or less steal her exact niche and do it BETTER after a point is a major strike against her.
Yuna: 10/10. I wanna give her lower, but I can't justify it; Aeons are just too damn good, and without them, she's still a Healer with good buffs, who can make a good Black Mage later on.
Kimhari: 6/10. Decently flexible, but he never quite felt good enough to justify higher. Also, crappy overdrives don't really help.
Fire Emblem Armors and Lancers:
Bors: 5/10. OK as a wall, but found him worthless offensively until he promoted due to Non-Sword Melee weapons sucking ass. He was much better when promoted, granted.
Wendy: 2/10. Bors with a shit load more effort required. PASS.
Barth: 3/10. TOTAL WALL! Good out of the gate at being that, never gets better or something.
Douglas: 1/10. Cost me so many freaking resets BEFORE joining, then got doubled by Bolting, FAIL.
Wallace: 4/10. Absurd Trump Card in Lyn mode, and even if not promoted, he's still pretty good there. Later...well, he's kind of meh, though, if you didn't promote him and manage to keep him alive, he's kind of alright.
Oswin: 7/10. Now we're talking! Tank, Lances don't totally suck in FE7, and is over leveled so especially strong out of the gate.
Gilliam: 3/10. Good defense early on, not much else.
Amelia: 3/10. Good potential, pain in the ass to raise.
Duessel: 3/10. Alright when you first get him, but he never gets any better.
Gatrie(9): 4/10. Gilliam only more useful early on.
Brom(9): 5/10. Overall better than Gatrie.
Nephenee(9) 7.5/10. Now we're talking! Never found her quite as absurd as others, but she certainly was respectable enough.
Devdan: 3/10. Not too bad, but he's only good for filling holes, and there's better characters for that role.
Tauroneo(9): 4/10. Alright for what he is, but what he is isn't much. Resolve is pretty neat though.
Aran: 7/10. Good tank in a team that DAMN WELL NEEDS ONE. Also has passable offense due to high strength.
Meg: 3/10. Feels considerably worse than Aran on all fronts; she doubles things he doesn't eventually, but not sure that's enough.
Tauroneo(10): 4/10. Dawn Brigade's version of Wallace in Part 1, becomes a generic high level prepromo for Part 3, falls off by a notable amount in Part 4, though is still usable.
Nephenee(10): 8/10. Ok, now here's where she kicked some ass; Swordmaster with a Lance and better defense, pretty much. This means so much more in this game where doubling is a lot harder than it was in previous games.
Brom(10): 5/10. Servicable enough tank throughout Part 2 and Part 3, but...that's about it.
Danved: 4/10. Pulls his weight in the Crimean Royal Knights while not being a burden, but after those chapters, he feels hard to justify using, especially since he competes with Nephenee and Aran.
Gatrie(10): 8/10. Why you don't give Generals good speed without compensating somewhere. Gatrie is a Mighty Glacier ON ROLLER SKATES!!! Good on pretty much all fronts...except move where he has some issues. That's actually pretty much his only flaw.
