Poprad probably will have better resale value. People don't seem to want to pay much for Surly's on CL. Not sure why. My guess is that Poprads will hold their value in the coming years if Lemond as a brand does not continue after the Trek dynasty.
I'd compare them to cars this way:
Surly=1971 Land Cruiser or 1971 Volvo
Poprad=2008 Land Cruiser or 2008 Volvo
I like the Surly (though frameset to frameset, probably a couple of pounds. That steel fork, ugh.), but it is dated in terms of technology and weight. There is probably not a decent quality heavier frameset sold today than a Surly.
If you're looking for a road bike, I almost think the Surly is better because it doesn't have disc brakes. Road bikes don't need disc brakes. If it really will be your road and trail bike, then the Poprad gets my nod. Then again, the Poprad with disc brakes might weigh the same as a Surly since the frameset is lighter. Hmm.
If I was buying the Surly, I'd build it up myself with modern brifters and 105+ with a nice light, inexpensive wheelset like the Forte Titans when they go on sale for just over $100. It'll end up costing the same as the Poprad, but at least it will be comparable. I did that for my wife's commuter and it came in under 22 lbs. Not spectacular, but better than stock.
You didn't mention Soma Double Cross. They're headquartered in your neighborhood too. Frame weight will be similar to the Poprad. I have heard though that the paint chips off them every time you look at one.
