In my shooting "career", I've have owned several of the aftermarket stocks, with, and without blocks. And the one that I've had the best luck with, is the HS precision. There is one caveat to that selection. The last Sendero I bought, was in 300 RUM. Well, that model came with the raised palm swell, and on recoil, the knurled bolt would scrape across my index finger, and would take a chunk out of it. I prefer the old style HS, over the new. I have two old styles now, and they fit my hand a lot better. It dosent help having mechanics hands. I haven't gotten around to skim bedding the two I have now. I skim bedded my 7STW Sendero years ago, and it absolutely made a difference. As stated earlier in this thread, the tolerances are very close, but when you skim bed, you instantly see the voids that were present. My nod goes to the HS. This is, as everything else, a very personal choice, sometimes price governs. Good luck in your venture. A lot of great choices out there. Dont overlook the laminates. Stockys has some great ones. The Bobby Harts are exceptional. Some come with blocks as well. Have fun.
