The first two guys look way better to me than the second two. I think the woman that beat me 10-3 would beat either of the second two guys, but maybe not the first two.
The woman (she's 30) that beat me 10-3 is, I think, a bit better than the players at 2:25 (in the second vid). I don't think those women would beat either of the first pair of guys, but I think they would beat either of the second pair of guys.
As for that second pair of USTA 4.0 guys. They seem more like the 3.5 guys in my league. I think the 4.0 guys in my league would beat them no problem.
But this is all just unqualified guessing on my part. Really, being a very inexperienced player myself (although I've watched tennis throughout my life), I have no well formed (or very informed) opinion on this.
But I'll go out on a limb and say that I think that the best women players you video showcased would kick butt.
