From LN:
Roller bearings, like ball bearings, will have service intervals, requiring future replacement, even if manufacturers claim otherwise. The only IMS replacement that is permanent and does not require future servicing is the IMS Solution which is based on the oil pressure fed plain bearing design used by Porsche for the Mezger engine's intermediate shaft.
And:
It is best practice to replace the IMS bearing as part of regular preventative maintenance. Depending on what bearing technology is used, service intervals can vary greatly, with the IMS Solution's oil fed plain IMS bearing is considered the best solution to prevent IMS bearing failures.
Personally, I prefer one and done.
I'm deep enough in this engine that I do not wish to be doing this work again on a regular basis.

The dueling excerpts. At the very least, LN's website contains contradictory information. A person who does her own wrenching is in a different position than folks who have it done for them. PIper6909 made a telling point about LN's requirement that the Solution be installed by a certified Porsche shop to qualify for their limited, five-year warranty. That would cost probably three to four grand, parts and labor. An individual's financial means factors heavily into the equation. I shelled out $4200 (including shipping), for a low-miles engine. Am I going to blow almost another two grand on the Solution when I can't install it myself without voiding the warranty?! Not bloody likely! I've heard nothing but good things about ceramic-hybrid bearings. Even Porsche guru JFP, whose credibility is beyond reproach, has gone on record in this forum with his approval of LN's Retrofit. That's good enough for me.
