Not sure about the others, but I had a KWA ATP for about two weeks, and it fell out of my holster from about three feet on padded ground, and it stopped functioning right. Slide wouldnt cycle completely and FPS was a disaster. And of course my warranty was void because I removed the orange tip. I ended up trading it for my friends old sniper and he ended up giving it away to one of his friends lol. So yeah, from my experience I wouldn't reccomend the ATP.
I diont know what your budget is, but the KWA M9 PTP is an amazing pistol. I've had it for over half a year now and its had plenty of much worse drops than my ATP, yet it still functions perfectly. Very high quality and rugged pistol IMO.
Anyways, that's just my experience. My ATP might of been a lemon... but who knows? Sorry I couldn't fully answer your question, but best of luck to you anyhow.
