meh Im lazy so I'll just keep it short
Seed:
Pros
good story line, good character development, exciting fights
Cons
None of the mobile suits seem too interesting to me (xcept freedom and that dog thing Waldfeld used)
rating: 9/10

Destiny:
Pros
nice beginning, nice mobile suits, nice songs
Cons
story line was shit, no character development, no explanation to most things, crappy reused scenes, crappy ending
rating: 7/10 (I think this series was made so they could sell more of their products. gay)
