yer tis a hard choice between those two. i would go for the vfc. if you want something like the 417 but without the big mags you could for the vfc m27 which is basically a longer 416.
yer im a complete fan on the 417, i really want one but i also want a m27 as they are both pretty unique and not overly mass produced. the internals are average but the 417 has the 2.2 gear box so its ait different and im not sure about upgrades for it. but i run a VFC SR16 and its about 3 years old and i have only just had to start playing with the gearbox
The V2.2 gearbox comes apart in 3 bits, I think to give you the correct angled grip. I absolutely love mine and I haven't upgraded internally at all. Very nice with li-po's. Great range and accuracy.
Magazines are very large but I run a hi-cap (500 rounds) and that's it! It's not light... Not small but it just works.
