Precision ground means you will be sure to have a uniform thickness on the spine.

Just my $.02
Of course, if you're sticking it in fire and start hammering, it won't make a bit of difference whether it was hot rolled or cold rolled or precision ground

If you're doing pure stock removal, it being annealed would be the major selling point for me. If it is not precision ground, that would be easily corrected with a belt sander. The exact thickness does nt really matter for razors. I think that is mostly important if you're using it to make tools that need to be an exact thickness, such as certain wrenches etc.
