We did MK in January 2025 and EPCOT in January 2026.
I really enjoyed both, MK is probably more bang for your buck and I would do it again. It was a good way to get a lot of rides in on a short trip where we weren't doing much other park time during our time in Orlando. Of course, it is not exactly the same as a regular park day if you are interested in dining, shows, etc. but my kids wanted to do all the rides including Tron and I really loved walking through the park at night with no crowd congestion.
I liked doing the EPCOT one as well mostly because we walked on Cosmic Rewind 4 times back-to-back, but due to the much more spread out nature of the park and less attractions, that was probably a one-and-done for us. MK I would do again.
