I would probably say in this order:
1. Variances (Percentage of swing on rails either way)
2. Rails and amperage.
3. Weight
Oh, and you can stick price in there somewhere too

Do you mean something that can be checked in the store?
How about the ratio of the combined power to the total power? I noticed that for some some cheap 400W PSUs it's only 50%, making them weaker than the best 300W PSUs.
I think that for PSUs of a given power rating, the size of that transformer between the two heatsinks may be a good indicator of quality, and I recently noticed that the cheap, wierd brand 500W PSUs at Fry's had transformers as small as the one in my best 300W. But I don't know what frequencies they used, and higher lets a transformer be smaller. My 300W runs at 95 KHz while most PSUs use 60 KHz.
