It's all a matter of opinion and taste. Personally, I am not interested in DW at all. I actually think they are the most overated drums of the past 30 years. I will say their public relations and advertising departments are great. The advertising and the hype they generate is incredible.
As for heads for birch drums? If warmth is required, I'd recomend coated emperors with ambassador reso's.
There's a strange thing that happens with success, some people are always skeptical and some just plain choose to dislike it.
I've got no problem with Pearl, heck I was always a Pearl guy from the start, Peter Criss played them so they were the first kit I always wanted to have. I got my Pearl Pro Series DLX Birch Kit, I got a second one later. Up until their latest change to their cymbal arms I have always thought that they have had the best hardware also (except pedals, though the Eliminator is very good). I always thought I would want a Pearl Maple kit also. Until I played DW's. I know it's a personal preference but in my experience the DW kits have always had just a fundamentally lower, deeper tone to them. So noticeable that in my opinion the even Pacific Maple drums sound better than the Pearl Masters, Tama Artstars and Gretch, at least better than the kits I had a chance to play. Just my story and my opinion.
The only other drums I have heard that compare are Pork Pie drums.
By the way, one of the ways I got my Birch drums to sound so good (noticed by bandmates and sound engineers, one of whom worked with Jeff Porcaro. Mind, I am only saying the drum sound, I would never think that my playing sounded as good as Porcaro RIP) was I'm lucky enough to live close to the guy who runs Pork Pie and I had him re-cut the bearing edges to my whole kit to the round-over cut (that DW also uses). It made a huge difference in the sound and they tune easier. Check out the Pork Pie drums website for info on getting your drums done. It's worth it.
Sorry for the novel.
