There are over a hundred distros, There is no reason to keep using one if you don’t like it. Use a VM to avoid multiple re-installs and be picky. You’ve got that luxury. Nobody is going to tell you how best to use your computer, unless you install MacOS or Windows.

It’s weird that Linux certification requires rote-memorization of commands. The only people who make any effort to memorize commands are newbies and people studding for exams. You will always have access to bash history, man, and --help, even from an offline machine.

Every command I’ve memorized is simply the natural process of repetition. Is that your experience?
