It just boils down to whether the GVWR matters to you or not.
If you want the higher GVWR for aesthetics or bragging rights or maybe it even has some legal significance in Canada or Antarctica or wherever, get a truck that comes with that higher rating.
If you want the 10k lb GVWR because of neighborhood rules or highway restrictions or whatever else might complicate things, get a truck that comes with a 10k lb rating.
If neither is important to you, get the best deal you can and don't sweat it - the decal on your fender doesn't mean anything.
