Cessna retracts give me the willies. Keep that pumping arm in shape, and pray that you don't lose fluid. IMHO, the Cessna retract design is the worst one in the class (that I'm aware of).
Before you make a statement like that run an AD search on the piper Arrow and then on a C-210, and for comparison the R182.
you'll see how unfounded your statement really is.
I'll make it easy. here is the 210-L AD list

IMHO I'll take the nit pickin rigging, and "O" ring replacements of the 210 L/G over the cracking Piper landing gear anyday.
