I prefer having separate 4 inch CNC vise (open much more than the 5" from Tormach) and a couple Glacern CNC 6"ers. MUCH easier to find accessories, actually come in matched height pairs, more room, more versatile, MUCH higher quality. You can't even purchase the replacement jaws that come with the Tormach CNC Vise. Mine broke and they sent me 1" thick jaws that limit the total opening to just over 3"... on a 5 inch vise... ridiculous.

They are $600 but to me they are worth it. The whole "5 inch fits better" is an epic load of BS since it only has a 3.5" throat when the jaws get replaced it is less useful than a 4" vise with 5" or 6" steel soft jaws as it will have a larger opening. I can put my glacern 6 next to the 5" Tormach and have more useful clamping space on the Glacern since it can hold a 6" (in the Y axis) part and still reach all of it.
