I’ve been diamond since the rollout. I definitely get MUCH faster pickups at airports (a stated benefit). I base this on years of experiences as well as a few “side by side comparisons” where I’ve been with people who request at the same time as me. Still no upgraded rides. Unlike another poster, I have found the ride price protection quite valuable. The price locked in for my route ($20.49 iirc) is about $2 more than the lowest I’ve paid in the last year, and very much in line with what is typical. Quite often the price protection is actually triggered, including at least one time where the fare would have been over $45. Do be aware that the price protection does have a cap after which you get only a partial discount. Given I was already a heavy Uber user, these are all nice bonuses. For some people, they may be worth switching from a competitor, especially for the faster airport pickups and price protection. The accumulation of Uber cash doesn’t hurt, either.
