What #Linux distro (with Gnome!) should I install next?

Currently, I use #Zorin, a polished version of Ubuntu. I still like its design, but there are two issues:

1️⃣ The upgrader sucks: When upgrading from v16 to v17, it didn't check for a sufficient amount of free disk space, which corrupted the installation. Now, the upgrade from v17 to v18 failed with an unhelpful generic error message.

2️⃣ Zorin is always at least one year behind #Ubuntu, which sucks because of compatibility issues.
