UK airsoft is just fine. It's a decent mix of rentals and noobs, Dye and Crye babies, geardos, Walts, and the actual airsoft veterans in jeans with random brand NBBs or a scruffy AK non-ironically held together with duct tape, all playing more-or-less happily together.
Power levels are fine too. I wouldn't be fussed if they went a bit higher, but they're not going there. Auto guns and bolties are both usable and distinctive. There's some debate over DMRs, in terms of both power and power-play abuse of them, but it's not a huge drama and sites are free to fiddle with their rules, or bin them off altogether.
When I hear about the competitive stuff from Italy, or huge sites and squad play from Hungary, nah, not for me, thanks, let alone the roid-rage flip-out-and-fite-IRL tosh from the Colonies. I've enjoyed a couple of light filmsims, but for a regular Sunday I'm fine with short games, short walks, lots of shooting toy guns and maybe playing a bit of dress-up, without some Major Issues barking orders at me.
