Original morph, just because of the awesome music in the background. If I had to choose one based on looks I'd probably have to say either Zeo or In Space.
MMPR Season 1 morph, Space and maybe Ninja Storm(Not thunder and samurai). I hate flashy morphs(cough splutter Dino Thunder, SPD, Lost Galaxy). I liked Time Force, but I saw timeranger's matrix sequence and fell in love with it.

i couldn't find one with RJ and Dom's morph
Edit: Oh I didn't notice Nightmere already posted one XD my bad

but I think zeo and space were the best with lost galaxy right behind them.
