I went the opposite way: I started with UHK, then went for a ZSA moonlander, but settled on a kbdcraft Israfel, which is a relatively cheap, split ortholinear.
I felt most of the extra functionality and polish that I guess makes up the massive costs of UHK and ZSA wasn't actually necessary. It was cool and fun and useful to try a bunch of different stuff, but then over time, I wanted things to be simple and small which UHK and ZSA Moonlander aren't (ZSA voyager wasn't at the time).
All I'm saying is if you've got comfortable with a cheap Corne, I think you might feel underwhelmed if you spend a lot on something a lot fancier.
