m97.2 (2009-2012) is the best of the bunch with DFI, no IMS, and 4 scavenge pumps in the heads. A much more stout engine from a design perspective. The 981 is better still. That said my lil 98 2.5L Boxster with 115k miles, 100+ track days is a great result for any platform. I think it is far better than I did with earlier Chevy, Ford, and Nissan motors that were taken to the limit often.
No engine platform is perfect and all of them have warts (even Miata). If it survives the factory warranty, it meets the minimum design requirements. If it lasts 3x the factory warranty, it is pretty darn reliable by modern standards. You can now buy 3 early 986 cars for the price of one good used 987.2 car. That is paying an extra $20k up front for risk avoidance if you buy the 987.2 car. $20k will buy a lot of tires, repairs and maintenance.
Choose wisely.
