I spent time with Bench Rest shooters as well, and there is much to learn. However, depending on how you use your rifle, some of it may be applicable, some may not. Super tight fitting cases in the chamber is not advised in a tactical or hunting situation. Still, these guys can teach you a LOT.
Regarding how well the Wilson die performs against thread-in dies, this article was informative. The writer is a very experienced shooter.

Also, the fact that dies can float in the Forster press vs being locked down, may also enhance the performance of threaded dies. In the test above, a Forster was not used.
I went out to the garage, took apart my Redding micrometer seater die to make some measurements. Just where was the seating stem touching the bullet?
I measured the length of my bullet, a 223 Remington Sierra 53 grain flat based bullet. I shoot short range and do not have the VLDs mentioned here, so not contesting what was said about the metplat touching the stem. It very well may.
Anyway, my bullet is .6955" long. The stem is 1.1915" long. The bullet and the stem together are 1.6915" long. This means that .1955" of the bullet is inside the stem, or the stem contacts the bullet .1955" back from the tip. On this bullet, the diameter is small, and would not expect this portion of the bullet to ever touch the rifling. Most certainly, the die seating stem could afford to contact the bullet further down.
I don't know who the Wilson and Redding (or Forster) would compare with the bullet I use.
Another thing about the Wilson. You do need to buy the arbor press, another $100 or so. But, a one time purchase.
Never used any other press other than Forster, but got it because that it is widely regarded as an excellent design with a very good performance reputation.
I agree a good scale is needed, and I use the RCBS 1500 scale and dispenser. I like it. Increased accuracy is welcome, but know that with increased accuracy comes increased sensitivity to everything, including lights, drafts, etc. I may still yet end up with one of those very accurate scales.
