George, haha! I can assure you, I'm not a Sigma rep😆. I actually love most of my Fuji lenses, including my 16-55 2.8, 50-140 2.8, and the 33 f/1.4 WR. Regarding the 33, I can highly recommend that lens. Unlike the 56mm WR, I've been thrilled with the 33 WR lens. In fact, the 33mm may be my favorite because it's speedy, has an accurate, responsive AF, and just produces great images. This is actually why I hoped and expected the 56mm 1.2 WR to be similar quality, but they honestly feel like they're from two completely different tiers of lenses, mostly because the motor on the 56mm WR is so loud and slow.
I'm also just an amateur/enthusiast photographer, and I just can't justify spending so much money on a 56mm WR if the AF is going to struggle so much. I have the Sigma 18-55mm 2.8 and the 56mm 1.4, and both have been stellar--somewhat surprisingly because they're so much less expensive. It's kind of hard to believe. My main beef with Sigmas is that they don't have an aperture ring, which is what I like about Fuji and Viltrox.
I also spoke with that same Fujifilm rep who discussed the 56 WR with me in-store (which, to be fully transparent, he said was his favorite lens in the Fuji lens lineup), and he said he would only go for Fuji and Sigma, not Viltrox. He described Sigma as budget, solidly built, and good IQ, while the the Fuji is more expensive, much better built, and has amazing IQ, but the Viltrox in the middle with subpar AF performance.
