These are the only tools I’ve used in earnest, so whilst I’ve heard great things about Déja Vu and MemoQ, I can’t possibly comment. I’ve been meaning to write about CAT tools for some time now, but before you all shoot me down in flames, I should start off by saying that I don’t claim to be a technological wizard! This is a purely personal analysis, based on my use of Wordfast Classic and Trados Studio.
