You know me, I'm usually the first one to jump on Unity when there's an issue. Been using 2018.4 LTS for a little while now on a new project and I'm getting more than I ever expected from it. Performance is great, with all the new features / tools it's put me in a position where I'm having to learn and expand into things instead of Unity being a roadblock. Staff have been super friendly and helpful (not saying they weren't before, it's just there seems to be less things falling into a black hole). Even though I'm using a fair few preview packages in 2018 at least it's been rock solid. I'm currently doing a 30 day project which will attempt to grind Unity to a halt, it's one thing creating a "tech" demo but it's completely something else taking said tech demo and making it a large completely archaic heavy hitting game that makes consoles weep whilst expecting it to run well. I'll create a WIP thread at some point that'll run through all the challenges.
