Wow, that's kinda unusual! :)
Personally, I prefer the more minimalistic designs and combos, such as MagiKing No.1, GekiTouja and Go-Buster Ace.

i do not hate toq rainbow because it's a cluster i hate that you make all the other mechs useless with armless and legless bots unless you bought all the candy toy/ gashapon versions of the trains and have those int eh toq rainbow formation

Personally there is something about ToQRainbow that I like but cannot pinpoint.
Other than that I like Gekitouja, Time Robo, Victory Robo, Shurikenjin, Galaxy Mega, and Dairenoh, Ohranger Robo. And Gosei Great as well. Out of these robots I just listed personal top 2 would be Dairenoh and Galaxy Mega.
