Man, this is tough. I feel like my answer could vary day-to-day, but probably one of Tallgeese/Epyon/Wing (Zero).
Ignoring my initial Wing repulsion I love all of Katokis EW redesigns.
I haven't seen any posts to the contrary on this (no clue if I'm in the minority) but I feel total opposite on this. I much prefer the Kunio Okawara designs from the TV series over the Katoki/EW redesigns, except for Altron. TV Altron looks like it was designed by an 8-year old ("And he'll have two dragon fangs, and a shield over here (on shoulder), and a twin beam lance, and a tail laser,
and wings"). It's too much and all those elements don't mesh together well. The EW version slims it down to all it needed to be while still making it look like an upgrade to Shenlong.
