Wow and here I was thinking this was going to be another Yagu V Tendou thread >_>
Ryotaro or Tendou? Who's the better main character?
Ryoutaro for sure, by now we knew Tendou was all about pointing to the sky and saying "I am the best". Ryoutaro has already, slowly but surely, more confident in himself, and is actually looking to actually being involved in the slowly unveiling mysteries of the show it's self, so yeah, Ryoutaro wins this by a long shot.
Hiyori or Hana? Better lead girl? Hana, she actually has screen time and is actually allowed to DO something than "I don't jump around when I go to shows, I must be Emo".
Storyline? Den-O or Kabuto - Ackk this is tough, cause unlike other people here, I have to say "What story" even around Kabuto 14. I know people complain about the forumlatic nature of Den-O but Kabuto seemed to be as big of a offender, with the whole "Worm shows up, mimics someone, Tendou does something seemingly unrelated until it ties in, Rider kicks worm." This might get me killed but I'm actually going to say Den-O on this one too, Cause we actually know the Imagins goal, where the Worms were just "Mimic, kill, mimic, kill" at this point.
Fights? Den-O or Kabuto - Well I'm torn yet again, Kabuto had better Cherographed fights, but I'm finding the Fights in Den-O more entertaining to watch, since Den-O isn't untouchable like Kabuto was. But I will give this to Kabuto for the Cherography.
Music OP/ED/BGM? Den-O or Kabuto - Oh God, Den-O. I like Next Level and Full Force/Lord of Speed, but Climax Jump DOES'T ABUSE the Synthesizer and I rather like the Jazzy BGMs of Den-O, more so than the Kabuto BGM's which were good.
Suit Designs? Den-O or Kabuto - Kabuto (At least the rider Forms) wins this, but Den-O's forms arn't that far behind though XD.
