OK I watched ep.1 of Macross Frontier & Code Geass.
Code Geass reaction: OK WTF England rules the world? Japs are elevens? OK whatever, girly main character umm... ok Rebels, fighting happens main bumps into old childhood friend in middle of fighting. Que mystic green hair chic she dies main does a 2001 stik and gets hack Death Note powers kills everyone. OK WTF DID I JUST WATCH? I MEAN WHAT THE HELL! Didn't make any sense at all even with info given in the beginning of the show. The music was ok not great overall just didn't feel it.
Macross Frontier reaction: Wow nice CG! Ok recap & history of macross nice touch. Nice bgm and the animation is really clear. Ok what the hell a cable car. School life ok homage to mac plus with hand movement oh ok. Girly main flies off wow nice flight animation and wtf Golden Gate bridge in background omg (SF native here) Main meets green haired moeblob and shows he's a bit butthurt about being called a girl thing. So concert starts and is sinked to combat action that's nicely done. Ok wtf are those things shit blows up. And back to big spaceship with city inside. Alien thing blows more shit up gets inside more shit blows up pilot flies out of plane cool then goes *swish* :P Main does heroics to save moeblob. The plot is standard fair for macross but it is done to a very high degree And the action was insane and I have to say it made me want to see the next show very much. Very much up to the standard of what you would want from a macross show.
So final verdict Code geass could not hook me and Macross F was made of awesome and win for XXX mecha porn. So that's my humble opinion hope it helps. :3
