I'd love rock solid UX that didn't change on each update - for instance drag and drop capabilites on blocks, not depending on toolbar location - before more gradients and other fluff.

Been a big advocate of Gutenberg since 1.0, as I liked is principles, but its really hard to keep people on board when UX is changing fundamentally.

That said, the nerd in me, enjoys the momentum of the Gutenberg development, and the increasing support from theme and plugin devs. Today its possible to create some really beautiful blogs, easily and for free.
