I guess I'll join. Airsoft: I've got a electric Classic Army G36K, a mini electric MP5, a spring Super 9 sniper rifle V1, a UTG NAVY SEAL MP5 A4/A5 AEG Airsoft Gun Version 1.0 (copy paste there), 2 spring pistols (both crappy models), and an electric X8 (it's a low quality electric so its name isn't worth mentioning)
As for paintball I don't own any but I have played and did enjoy it some.
More info: I'll play airsoft at pretty much anywhere it's allowed (my house, grandparent's house, cousin's house, etc.)
Although I've been playing for 3 years and I've gotten very nice guns, I'm still only an amateur whilst one cousin I have is practically imune to pain, has very highpowered guns (one has 450 FPS), and is merciless so I'll only battle him sometimes.
Favorite battles: I once had 7 people over and we had a battle with low quality guns (minis, pistols, low quality springs, and my Super 9). It was total chaos as most everyone had bad aim and there was lots of cover. My entire yard was filled with pellets by the time the battle was over.
Me and my 2 cousins were having a battle in my Grandparent's barn and the field surrounding it. I was in the barn's second story using my G36K (it has a 3X scope and a 130ft range so it's a great sniper) while my cousins slowly advanced by crossing behind cover. Then the next tree for them was around 50 yards away, so they both made a dash and I switched to full auto. It was like Omaha beach on d-day, the soil kicked up all around them and I managed to take out one and I used a full 450 rounds. Then the other one stormed the barn sneaked up the steps and shot me.
As you can see I clearly prefer airsoft.
