It depends on what your own opinion is. Ours doesn't matter.
Go with what YOU want.

Fi3re is right, it's more difficult to find aftermarket parts for any gun than the M4. M4's are so common you'll find all sorts of stuff for them from every airsoft retailer. After market parts are available for the sig 551, RIS handguard, top rail collapsable stock ect. but they will be harder to source than for any M4. I personally like the look of the SIG and don't want a lot of crap on my gun that I don't need or use for the sake of it. But thats just me I'm a minimalist and I want to keep my gun light. That being said the Sig comes with removable rails for the handguard if you want to mount a flashlight, PEQ box or vert grip ect.
I won't try to steer you in any direction just say that I am happy with my gun. I think both guns are good and you'd be happy with either.

Edit: if you can try to get your hands on both of them, pick them up shoulder them see which one feels most comfortable to you.

i know that styark and thanks for the reminder, however its nice to hear people speak so passionately about there guns, so now im basically down to just what i think looks better to me. Thanks a lot guys, hopefully ill have some pics up of either one of these soon, depending on which way i go!.

Shadow I'll be at Sgt Splatters on Sunday 7pm-12am if you want to see the ICS Sig in person. http://www.airsoftcanada.com/showthread.php?t=121441


Edit: There are rentals available if you want to play and spectators are always welcome if you just want to watch.

i just might take you up on that one man ! thanks.

Btw, how much are rentals man ? i may just play.

If you're going to get a Sig, get a G&G. Best one out there.

hmm only problem is the place i was going to order my gear from doesn't have the G&G, mach1airsoft, thats who i primarily wanted to deal with, unless you had another place i could go to thats trust worthy and fairly good prices ?

Well I would recommend a seller on here but you're not Age Verified. The only other place I know that sells the G&G is BuyAirsoft.ca

And yes, it might be more expensive than the ICS (it's $600-$700) but it's worth it. Trust me, I have a real one, and I've handled the ICS 551.

Thanks for the input man, i plan on heading down to TTAC3 tomorrow to get AV'd

I think it's $20 for the rental, are you a member of Airsoft Ontario? http://*********************/forum/index.php

If not sign up and contact Thenooblord he rents guns. He has a temp ban from ASC for being naughty lol

i wasn't but will do now *nods* ill get in contact with him tonight and see what he offers, hopefully ill see ya out there sunday! whats the cost of BB's ? if you know off hand.

bb's are around 10 bucks a bag for bbbastards (best brand imo). But you will have to find someone that sells them or buy them from a store.

From the sound of it I dont think you really know how airsoft games work. We (or the host) arranges a deal with a paintball venue. We bring our own bb's and everything. The venue has nothing to do with airsoft rentals, equipment rentals or sales of bb's.

Thank you for that, i was a bit fuzzy there but you cleared it up man, thanks *nods*

VFC is one of the best high end companies out there and yes the SOPMOD is one of the better rifles too, its not the E series which is the budget series, Go with VFC, they beat ICS anyday in quality control and durability, internally and externally.

I got the vfc m4 and its just awesome, solid as hell, good internals/stock accuracy, good compatibility. no complaints at all, except that my wires are a little too long in the back and its hard to cram them in there when my stock is not extended.

compared to the SIG its not even in the same league.

my buddy has the SIG and its okay but overall quality is less. Also not as good of an outdoor gun as the barrel is quite short.
