On his drawings, Ishida writes his pen name as "SÜI" (it's not really all-caps, but he writes the letter i without a dot).

Well, we only have three titles that we can consider: 東京喰種［JACK］ 東京喰種［JOKER］ 東京喰種［zakki］ All the other titles of this form (the chapter titles) consist of kanjis (except for that oneshot "Rize", which is in katakana), so we can't really use them as references. JACK and JOKER are related, as they're both playing cards, so it's obvious to write them the same way. Nobody ever asked Ishida on twitter if he consciously chose to write "JACK" and "JOKER" in all-caps, so I can't give you any clear evidence. But I know how extremely meticulous Ishida is in choosing these titles in square brackets, I'd never try to second-guess his choices. He was even playing with this format in the last chapter, where he chose the title [研  ] instead of [研] (BTW, the chapter article isn't reflecting this). And it's a bit biased to say "zakki" is a style choice and "JACK" is not, as they're using exactly the same title format: 東京喰種［xxx].

But I don't want to start an argument about this, so do whatever you think is right.
