Yes, the full version of the UMC is the best portable EVSE I own(ed). I like it so much I own two. However, your theory that I'm angry at Tesla for nerfing the UMC is false.
1) I already owned a full version UMC prior to purchasing the MX, along with a TeslaTap J1772 reverse adapter.
2) I knew they nerfed the UMC prior to purchase.
3) I knew they ran out of 14-50's and were scalping them on Ebay prior to purchase.
I made an observation. It is very common on this site for people to get angry at facts, that's why it has a dislike button. Feel free to put up a dislike, thanks!
The Chevy Volt EVSE also runs off of 90-265 vac, but ships with a L1 pigtail. That doesn't make it an L2 as sold.
