Basically I have enough money to buy either a Line6 Toneport UX2 or the Guitar Rig Kontrol 4 Hardware. I'm going to be using either one of these with programmes like Amplitube and Guitar Rig and I'd like to know which would be the better option to buy, are there any differences between them? Does one have a better recording quality or lower latency e.t.c

Any help would be greatly appreciated
Never heard of the Guitar Rig but I have a UX1 and it's perfect for quick and easy recording. Decent range of tones however you'll have to play with most to get the best out of them. Only let down is a lot of the tones I've tried to download through GearBox need extra tone packs which are around $40-50 minimum but that doesn't really count for much, still a great interface/
