We're talking like $50 compared to $500, or something like that. Wish I read that before I bought a $150 or so POS from JEGS... I'm a fan of HF, but generally ONLY when the tool will pay for itself in a job or two. Cornwell is a nice company. Then again, I once bought Snap-On jumper wires in a fit of tool truck weakness.
I currently own both, so here's my take (as someone who does not like to spend a ton of money on things):
The HF impact I have (it was the top one they had about 3 years ago) I got to lug to autocrosses and such. I've found that it's fine for doing lugnuts, but is not up to any real hardcore tasks, including large suspension bolts (like control arms) and such, especially if rust is involved. It was $60 IIRC and I don't really consider it to have been worth it, in truth.
The SnapOn impact I have I actually got secondhand from a buddy (for only $300!). The batteries were on their last lives so I had them rebuilt. This gun hasn't met anything that it can't remove with little effort. I've even done big 1" rusty lag bolts bolted into 8x8's, which I couldn't even budge with a breaker bar. I consider this to by my "best" tool in terms of reliability, usefulness, and overall awesomeness. I would gladly pay full price for a new one someday when this one finally kicks it.
That said, I own very few other tools from SnapOn or Mac, because I can't afford them and can't justify the price for most other things.
