Over the years I've used many different types of vises and my opinion has been it makes no never mind, just go with what you have they all work pretty much the same. I can't say that anymore, the BenchCrafted metal screw with their crisscross takes bench vises to another level. I just finished changing out a wood screw vise with a guide to a BC metal with crisscross and it's day and night.
