I play on the last release - 1.14 (.2 to be specific), I don't quite consider 1.15 to be a version yet until actual release, I don't count pre-releases. I'll probably be sticking with 1.14.2 for a while as I see no reason for me personally to update so far. Like Toadrunner I don't care for bees and honey blocks so will be skipping this next release as it holds no interest for me. The Nether update does interest me though, greatly so and way more than bees and honey, although it's doubtful I will upgrade my main world to it as I have nether routes and stuff I want to retain as it is. I'd rather make a new world for the new nether.
I also am happy to wait for biomes, and not just the mountain update from this year but, the other ones they've supposed to have added by now. 1.14 has the benefits of the update aquatic for me from 1.13, and while the village and pillage update can be cumbersome, there is plenty more me me in terms of blocks and stair varieties, campfires, barrels, some (Not all) work stations and of course bamboo for scaffolding. Plenty of reasons for me both building and crafting to update.
