The Bellroy, once you accept the simple fact that it isn't an overly protective case, is absolutely fantastic for the Pixel 6 Pro. The Bellroy for the Pixel 6 is a different design which is still exceptional, but only if you don't mind the complete lack of protection at the bottom of the phone (which is completely open aside from the corners, unlike the 6 Pro being enclosed).
Leather is top tier - feels great, looks great, and will develop amazing patina after about a year (at least, based on my experience with the Bellroy for my 3 XL).
As to whether it's worth the price, that's debatable. Just note that any of these luxury/premium/vintage/etc "leather" cases you see for under $20 are going to be vegan, PU, or other synthetic leather, and, aside from being less durable, will look worse over time rather than better. Of course, they're a LOT cheaper, and for don't violate personal ethical mores held by some.
