Glenn vs Rei: So yeah, the SUPER AWESOME Glenn damage which is near OHKO relies on him getting double Einlanzer while everyone else is stuck with Stone. It's quite a bit easier to get a prism weapon than double Einlanzer (which requires two separate sidequests IIRC) so fuck that. Difficult to estimate exactly what this does to Glenn's damage, but looking at the effect of 5 str on others I'd imagine Glenn's relative damage falls by about 15-20%. So yeah, lol at Glenn OHKO hype, Rei uses ID.
Glenn vs Dias: Faster, has some evasion.
Glenn vs Angelo: Quite a bit faster.
Glenn vs Flik: Hits a weakness. Ow.
Glenn vs Jude: Halves wind, is tanky, so may well drop Glenn to a 3HKO, and may not need to. Too lazy to math this out to be certain.
Glenn vs Sabin: Nope, another case where less respect for Glenn's damage costs him a match. I think opting for a Tiger Mask, which only he and Gau can do, will get him just past Glenn in speed.
Glenn vs Meru: Okay, someone Glenn OHKOs even for me!
Glenn vs Alice (SH): Halving physicals gives her time.
Glenn vs Seifer: When CC fights FF8, bet on CC every time.
Glenn vs Crono: Red Katana Crono is still faster and 2HKOs due to hitting a weakness.
Glenn vs Samurai (FFT): Speed, endless resources and not being worried about BG means he should take this.
Agate vs Rei: One-rounds. Think this is true either by Snowfire views or Dhyer views.
Agate vs Dias: Think so.
Agate vs Angelo: Bounce stops petrify nonsense, Buff stops any hope of a OHKO (don't think this is needed), and one of confuse/blind/death is getting through to mess with things long enough for Angelo to outslug. Superior speed also helps. Angelo speed kinda underrated incidientally (or at least, I've been doing it), he's only a hair slower than Jessica with Mercury's Rapier (lol like he equips anything else ever).
Agate vs Flik: Zappity zap.
Agate vs Jude: uhhh do Agate physicals even break Jude's special armour? I think they just miss. That's ugly, if so.
Agate vs Sabin: Faster, 2HKO. Just durable enough to survive Agate nonsense.
Agate vs Meru: dat frontloaded damage
Agate vs Alice (SH): edit: Earth Guard nonsense.
Agate vs Seifer: Can backload his damage well enough, I think.
Agate vs Crono: Agate needs 3 turns against the somewhat durable Crono, and Crono doesn't let most opponents get that many.
Agate vs Samurai (FFT): Earth Guard nonsense. EDIT: Or not. Agate isn't -that- much faster and his MP sucks, so he burns it up fast trying to do this. Meanwhile Samurai probably 3HKOs even with a stone-blocker (4HKO at worst), and that damage sticks forever while Agate either faces Blade Grasp or uses MP to do damage (which gets easily healed since Trails non-finisher damage) and needs three attacks before a finisher will KO, before Protect.
Agate 4-7
Glenn 3-8
