i love FN rifles, i really do, i love both my FNFAL's and they shoot flawlessly
but in this case, i think i'd go for the HK instead, just because of all the parts i'd already have laying around that could be interchangable with the HK rifle.
i've also talked to two german soldiers about the HK G36's. seems like general concensus says that the HK G36 is a piece of crap. they told me that they're much less reliable than the G3's that they used to use. according to them, little things on the rifle just beaks all the time. it looks good, but that's about all it's good for.
but still, long live FN!!!!!!!!!!
