As title says. Obviously I could setup different virtual machines or spend the time and install all the DEs in one VM if it is even possible without breaking the OS. I’m wondering if there is an already made iso or something that installs all the maintained DEs for trying.
Can’t say I’ve seen that yet, but it is a good point. Your home directory might still get a little messy. I think the thought of using the config to me a user per-desktop environment you test is problem a good idea.
