All you really need to know about Tachibana-san is that he is
a) A Traitor
b) The red one

Chalice's design is probably my favourite of the suits we have, but tbh, they've all grown on my immensely. Chailce wins because of the hearts theme, I think. Garren is a close second, partly because meme, and partly because "Red Diamond leather stag beetle gunslinger" is just a cool design. Blade's body is neat, but the head, idk, something about it, as others have mentioned, is a weird one.

As for Kenzaki being the best, he really is pretty trusting. He barely knows Kotaro, and here he is, being best buddies with him (after his old best buddy betrayed him, but still). Hajime is very purposefully mysterious at this point, and I probably didn't warm to him fully till a point in the future I'll mention, but ya gotta build intrigue somehow. Especially since you seem to be going into this with far less foreknowledge than I had, so this is dramatic tension 100%.

As for Kakusei... Well, it's no [CENSORED FUTURE INSERT THEME]. Or [OTHER CENSORED INSERT THEME], but it's alright. Chalice's little guitar riff is sick, though. Threatening, but not evil, as such. More just symbolising 'danger'.
