They are both top quality boards, both offer high performance, and I have never personally noticed any difference in the eye logic or trigger response between the two, but that may just be me. As such, I base my own choice of boards on what I think constitutes best value, as both boards get the job done - to my mind the Tadao board offers more, and as far as RRP is concerned at any rate, costs less, which is better value.
Virtue offer some features that the Tadao board doesn't, and the Tadao board offers some features that the Virtue board doesn't, so you may find that one board has specific features you want or need, in which case that makes the decision much easier - well worth having a close look at the feature set of each board if you have something specific in mind.
Personal preference though? I prefer Tadao.
