A bit early for a review, but...
I finally got my 2nd MK3S and 1st MMU2S in the post. I preprinted the print tower buffer on my other MK3S so it would be ready because I didn't want the 5 rolls of filament spread all over the desk, so I can't tell you how the OE print buffer works, because I'm not using it.
After a long build, I had a couple minor issues out of the gate. First issue was the MK3S wouldn't complete xyz calibration, saying x was too short. This was my own fault as I neglected to run the PINDA sensor cable correctly. Next it crashed trying to calibrate z. The print tower buffer gets in the way so had to remove that. Then calibration went perfectly. I put the tower back on and loaded some filament.
The next issue I had was on loading the filament, it would push to the nozzle, then pull it back repeatedly. This was the IR sensor not always reading correctly. I moved the chimney as best I could, then found that if I wiggled the sensor it would trigger, so shimmed it with a piece of paper. Now it works correctly.
10 hours into my first print, I got an error and had to intervene with the MMU2S. I disconnected the PTFE, cut the filament, tossed out the end, and reloaded. Not sure what was exactly wrong, but this seems to have worked and back to printing.
The purge block looks to be bigger than the print as well, but I guess that's just part of multi colour printing.
All in all, yes, it is more work and needs to be checked on from time to time, but I like my MMU2S and will continue to use it for some fun prints.
Here's a picture of my first print chugging along...it's a Mario mushroom guy.
