I'm not exactly 100% as to the real thrust of the OP, but I'll do my best.
Fact is, 90-something% of players can't tell MC from MTP, that's the reality. Therefore, at brand new UK retail prices, you can spend £400+ on a set of Multicam G3 combats (or even more for rarer cuts and patterns) and those 90% at a skirmish won't know you're in anything different from the £70 set of TMC combats or possibly an even cheaper set of surplus PCS MTP uniform. Personally I give zero fudges, I pick what I fancy out of my wardrobe the night before and wear it. If you go to an extended game with tougher rules maybe where you get a different sort of crowd, then yeah you'll encounter maybe 50% (ballpark) of people who can tell MC from MTP, but then they're all going to be wearing it too so it's nothing special at that point; not that it was special before.
It's pretty tricky at this point to find a camo that nobody else has ever posted on Instagram. But if you wear any Russian stuff, Australian, Canadian or any almost European pattern (M90, CCE, M84, wz.93 etc) you're pretty likely to be the only guy at a game in that pattern. My personal goal as far as choosing clothing for a game is just to be comfortable and test out as many different brands as I can so I can report back on that item, either on youtube or my page. I've collected lots of different colours and patterns but collect is the operative word, most of it has never been worn in game.
It's made from genuine Crye precision multicam whereas the others are just their standard 1000D nylon which is why there is such a massive price difference.
Warrior (and tons of other brands) use the real fabrics and are far better built overall than FLYYE. An airsoft-only chinese brand like that costing £400 retail is
pure price gounging BS by someone in the supply chain, there's no reason at all for it to cost that much. The WAS Recon PC is £130 new from UK Tac - there's not £270 worth of superior construction quality in anything from FLYYE; the fact it has plain coyote webbing for starters puts it in the cheaper production category. 1000 and 500D cordura in Multicam only costs slightly more than the same mil-spec fabric in green or coyote. Actually (quick browse later) a yard of 1000D Multicam is about $18, the same fabric in khaki is $14, you're talking maybe 6-7 yards max (and I'm being generous) to make that carrier, meaning a price difference of ~$25 for the manufacturer to get the different materials from the supplier, and those prices came from a small-quantity retailer, commercial suppliers that only sell in large bulk would be much cheaper per quantity.
Apologies if this comes across as bashing on your personal kit, I'm not, if it works for you in games it works, but that pricing at Mil1st is just insane. You can get Crye, Ferro, Blue Force and FirstSpear plate carriers for much less than 400.
