As for me, I main Akira. But would like to learn Jean, Sarah, Eileen and Lei Fei. I know Jean a little, but the other 3, I have no idea really lol. I like their fighting styles the best.
Akira was the first character I learned when I staryed back in VF5, and I never really strayed away from him. I used Eileen some, but she has totally changed (imo) in FS. So I don't know her like I used to. She just has a lot more stuff, so I was like, "ehh, don't want to re learn her" lol. But she's a fun character and has some cool outfits.
Might as well throw Jacky in the mix too. He's as slick as they come and reps that Jeet Kun Do fighting style well. Lots of fast moves, can hit you from a lot of different angles, and is smooth while doing it. Has lots of traits, but man that dude is crazy in the right hands. He seems good at getting in and out too.
Sometimes, just watching people use other characters on stream or in game makes me want to pick them up. It's a shame more people don't play this. It's really fun once you get the gist of the system.
Late, but still on time.
