Fullmetal Alchemist no contest,nothing can compare to how amazing it is!..though Full Metal Panic is good,but it's still doesn't compare to FMA for me.

I've seen a few eps of Full Metal Panic and compared to FMA it's nothing. So as MCHopnPop said "no contest"!

I agree with both of you.

i havent seen fullmetal panic yet haha want to

Being someone who hasn't watched FMP, I don't really have to say what I'm about to say, but I just want to comment on how I don't think those two should be compared like that. Other than name, the two plots are completely different.

One is about two brothers set on a hard journey to restore the lost bodies and beating up some villain on the way to their goal, and it's set in a parallel world of about a century ago. The other one is set in a modern parallel universe, and doesn't have the adventure vibe in it.

From what I know about FMP, I see it being closer to Code Geass (though I have no idea), and as for FMA, I've yet to watch an anime similar to that.

I haven't seen FMP yet, but I love FMA <3.

That was hard, I really like both but I slightly prefer the cheesy over-the-top mecha nature of FMP!
