I don't really have a preference. My 360 came with wireless controllers, and I picked up the rechargeable battery packs with the wired chargers. I lay on my bed when I play, and the distance isn't anything ridiculous, so I just leave my controller plugged in. If I'm laying in bed watching movies on my 360, and don't wanna get tangled in the wire, I'll unplug it. If a millisecond of lag kills me, then so be it; I don't play for money or anything where it's my livelihood.
