Well me, I am/was a big Gundam fan. I used to love mech-related stuff when I was a preteen (LOL a girl who loves mecha stuff xD) and I still do but not as much.
So, I've seen all of GS and almost half of Destiny and without a doubt, I prefer GS.
Well in Destiny, Shinn was supposed to be what you would call a "main character." But then Kira came in and "stole the spotlight." The plot was okay I guess but the romance thing went overboard on Destiny.
There were romance in GS but that was just fine. I can handle GS romance but Destiny romance was.. ugh.
So... which do you prefer? And why?
