When I was at asads with Simon a few weeks back I tapped up a few of the Uzi pro bats, I'm not sure on the profiles but they all tapped up fantastically regardless and pick up was very good, they felt like they'd take a couple of nets to get to their best but that was all they are pressed very well. All the Hell4Leathers I've seen have been pressed fantasticallly and to go from the start, the press isn't super soft but isn't hard it's a good mix so the middle is cannoning from the word go but with no need for stupid amounts of knocking in. B3 would be the firmest out of your selection, however I'm sure with a couple of coats of oil and knocking in with a few net sessions they will start to perform just as well.
All 3 are good brands and your almost guaranteed to get a good bat, the uzis and H4Ls will offer you instance performance where as the B3 will take a little while to reach its best so it's up to you what you want in terms of performance no longevity. If looks are your thing though the willow Matt has at the moment is absolutely stunning as mentioned in several other recent friends, so h4l would be my choice if you wanted something that goes like stink and looks fantastic as well, but I feel all 3 can offer you a very good bat
