Hey again 😉
On the AEG front the budget contenders are JG (JingGong), CYMA, Double Eagle (very good for certain models) and SpecnaArms.
Generally you can get a decent performing shooter for £120-£200 so I'd guess prices have come down a bit with quality and performance going up a bit.
Probably the main difference with AEGs are the batteries as we generally use LiPos now with intelligent chargers. More power in a smaller package.
For GBB pistols & rifles the most common is WE-Tech (WE). Decent performers but materials do tend to wear relatively quickly. TM are still going strong and GHK are highly regarded.
I'm sure others will chime in so maybe we should do a poll of everyone's opinion for the rankings
