The 5000 people involved in the class-action lawsuit against Lycoming
for defective crankshafts might beg to differ with you. They've
already suffered through multiple factory recalls and experienced
considerable down-time and personal expense.

Subaru engines were originally designed as airplane engines, too,
Notice the horizontally opposed arrangement of the cylinders? From
their web site:
"Fuji Heavy Industries Ltd., (FHI), traces its corporate lineage back
to Nakajima Aircraft Company, which was founded in 1917. In 1953,
five Japanese companies joined to form FHI, which has grown to become
one of Japan's largest manufacturers of transportation equipment...
"Best known for its Subaru automobiles, FHI also manufactures
commercial and military aircraft and aircraft parts, engines and
machinery, buses and rolling stock. The company has a long history as
a technological innovator and boasts some of the most diversified and
advanced all-wheel drive (AWD) technologies in the world."
The certified engines have stagnated in both technology and
materials. The Continental TSIO-360 in my Piper Turbo Arrow employs
almost exactly the same design, materials, and manufacturing methods
that have been used since the 1940s. Has any new engine design in
the last 50 years used mechanical ignitions?
I have a great deal of confidence in the that Continental engine, but
to say it has experienced "improvement" and "advances" is laughable.

With the exception of gearbox issues, you just described my previous
ownership experience with a Lycoming engine. OK, so the problems
were with fuel injection and the cooling problems related to baffling
in the cowling, but the headaches are there either way. Add to the
list several failed alternator couplings and loose magnetos and it
quickly becomes obvious there is no "higher ground" in such a debate.
