I'm not much of a Kool-Aid drinker (I prefer beer myself), but I've tried numerous methods of removing primer crimps. If you want to cut 'em out, use the Hornady (the Lyman tool truly sucks), or a quality case chamfer tool (be careful so that you don't remove too much).
If you prefer swaging them, the Dillon is great and gives you primer pockets with the easy seating that you would expect from virgin, uncrimped commercial brass.
My personal choice would be the Dillon, especially since I didn't have to actually pay for it.
The Hornady system works very well however, and in my opinion, will result in fewer cases lost to having "overprocessed" primer pockets than you'll get with a case chamfer tool.
I've never tried the CH4D tool, but it sounds good (eventually I'm gonna have to return this Dillon...).
