I've played extensively using both since I play on a laptop and move areas often (I've done a bit of traveling the past few months)

Wireless lag has been noticeable to me in some cases, sometimes everything in-game will stop moving for a second or two.

I've also played tethering my phone for LTE, in some ways it was far more reliable than some wireless I've played on (and I'm not talking public wifi hotspots)

It all really boils down to how good the router is & how good the internet is really.
