I think we should start make an actual chart to agree on. Lots of people seem to think Algol is the best in the game because he 'owns' so many characters, but I don't really think that's the case. I'll start on a matchup chart and we can go from there.
Algol Vs:
Amy - 4:6
Astaroth - 5:5
Cassandra - 5:5
Cervantes - 4:6
Darth Vader - 4:6
Hilde - 4:6
Ivy - 4:6
Kilik - 4:6
Lizardman - 6:4
Maxi - 7:3
Mitsurugi - 6:4
Nightmare - 4:6
Raph - 5:5
Rock - 6:4
Seong Mi-na - 5:5
Setsuka - 4:6
Siegfried - 4:6
Sophitia - 5:5
Taki - 7:3
Talim - 8:2
The Apprentice - 4:6
Tira - 6:4
Voldo - 5:5
Xianghua - 4:6
Yoda - 5:5
Yoshimitsu - 6:4
Yun-seong - 7:3
Zasalamel - 4:6
I don't think my list is 100% accurate, but I think it's accurate enough to start a discussion on and modify it from there. Some of the ones that I'm not really sure on are Sophi, X, Tira, and Yoshi. Also I used to think vs Voldo was in Algol's favor, but after fighting Manta at Evo I really don't think it's that bad of a matchup for Voldo. He's got really good tools to get in on Algol if he combines them with good GI use.
Whodat: Algol's up close game sucks compared to Amy's. And since the bubble shield is pretty useless against her due to B+K and some of her other bubble evading moves, he'll be forced to fight her up close most of the time. And since his step is horrible she's even harder t deal with up close, since stepping is usually the best way to deal with Amy up close. The matchup is definitely in Amy's favor.
