I have both an Aldred butterfly and a h4l devil. They are both pressed very well, finished very well and perform very well. Either way you will be pleased. Between the two I would go for the Aldred. The Aldreds tend to be heavier though pick up very well. If you prefer a 'light' dead weight you may have more options with h4l.
I have never had a B3 though the ones I have seen have little/no bow. That may or may not be an issue for you. It is for me, that is why I gave my 50% off voucher away. I'm sure they make an excellent bat too.
