Although I don't have any direct experience with White's semi dress, I've heard others rave about them. In many cases, people prefer them over the 1000 Miles because of their awesome durability (especially the lug soles). I've also heard people say that White's construction is better than Wolverine's which improves the boot's longevity as well. I can't speak to fit, but others seem to hold them in high regard.
I like the looks of the 1000 Mile's more, but White's is undeniably an awesome boot.
