Everyone's entitled to like and dislike whatever they choose, for whatever reason.
That said, stag scales are traditionally thicker, at least at their center, than the bolsters. Primary reason for that is that you want the rough part of the stag to remain intact, but the ends look better taken down smooth. Granted, the Kiwis would look better if the scales were a bit thinner overall and were brought down to meet the bolsters perfectly. They'd also look better if pains were taken to match sides. But doing either or both those things would definitely add considerably to labor costs and probably increase waste as well.
Unlike wood, you cannot "book match" stag. I can tell you I spent a good twenty minutes at a vendor's table picking out the two pieces I sent to SFSW for my custom stag Kiwi. I can also tell you I've seen worse matches on knives that were an order of magnitude more expensive. Do they look as good to me as my SFSW one, no, but I have to admit leaving them thicker at the ends retains more of the textured surface. Do they really look any worse that the micarta "blob" on a Viele II, or the partial scales on a Phoenix, Volpe, or Sebenza, not to me.
Good news, at least for some, is that the screws are the only thing holding them on, are T-6 Torx, and are not doped. So they come off quite easily should one wish to either invest some time in fitting the stag or replace it with something else. Bolsters are just about 1/32" thick. I think that might be a bit too thin for stone but SFSW may prove me wrong. Wood, micarta, or some thin CF, should work quite well.
