I’ve had many tubeless wheelsets in both materials. In that price range I’d opt for either a set of custom laced Easton aluminum rims with White industry hubs by the amazing guys at November Bicycles, or a set of carbon wheels from light bicycle. Not sure how the wait is going for LB out of China, I bought mine from the North American distributor as I wanted Industry Nine hubs. Got them for under 1500 with that set up.
personally I don’t see any reason to spend more. My LB’s are going 2.5 years or so used 3-4 days per week with no issues. I do live in a flat environment so can’t speak well to braking in rain or hills. If you have a lot of wet weather riding I would definitely recommend aluminum rims. My back up set are alu set up tubeless on my vintage bike since i enjoy the ride much more
