I believe all but the ART will give you low latency. I say that about the ART because it states in the ad, "no special drivers needed". Kinda like 'plug and play'. It may be fine, though.
I use an older Focusrire Saffire and it has worked almost flawlessly for... 3 or 4 years.
I've heard good things on these forums about the Scarlett, too.
Shucks, I'll go ahead and say it; get a Focusrite.
You might want to pose this question in the Cakewalk Hardware forum for a wider range of opinions.
