The MS hotend doesn't require any craziness to get to print good. Do remember to increase your temps about 10 degrees over what you were previously printing at (as recommended by MS).
If you are having issues it is almost certainly because of the 0.2 mm nozzle. To print with the 0.2 mm nozzle you really need to upgrade your extruder gear, the stock one is crap. It takes more force to print through a 0.2 mm hole and the stock gear just isn't up to the task.

I did all of those upgrades plus the extruder gear change. It prints great and highly recommended. The microswiss machined idler stuff is nice but I'm not sure how nessassary it was. I have that fan and have had no issues with 11+ hour prints.
Edit:
I added these split Zaxis couplers. https://www.amazon.com/dp/B01HBPHSII/
I added this gear: https://www.amazon.com/dp/B06ZYG5Z47/
And the Zaxis brace kit from GulfCoast also.
I've been pretty happy with these upgrades.
I added the Z probe for ABL and used a PEI sheet vs the old sticker. I tried the glass and had good luck until it chipped...too much abs adhesion with the juice.
Some things to look at:
The feed gear may be partially clogged with filament ground off during earlier jams. Inspect and clean if necessary.
Some feed gears have a rather rounded aspect on the gripping face. I prefer ones which are sharper, almost a knife edge. These from Amazon look decent but I'm just going by the pictures and reviews.
While you're in there with the feed gear, inspect the mating between the cooling bar and heat sink. It's critical.
Also between the top of the thermal barrier tube and the cooling bar.
Is the hot end insulated?
A small fan blowing into the printer can help.
The symptoms of a print that starts okay, jams halfway, but where the filament can be forced down by pushing on it is a classic description of a heat creep induced cold end jam.
