Considering your Mac is using entirely PC parts (excluding the BIOS, which is the only difference ) that's a pretty stupid statement. Also, I can link you to Mac support forums of iMac users having the same SSD migration headaches.
I support Mac and Apple end client devices in enterprise environments and their failure rate is just as bad as any PC with iMacs having a higher failure rate than Dell Precisions in our offices. Mac networking stacks are far, far worse to deal with than any Windows machine. I'd also like to point out I've never seen an Apple product in a data center either. My Windows products conduct business operations in the form of servers and hosting corporate databases while the Mac devices stay primarily attached to critical things.... like iTunes.
I'm not a die hard fan of Win10, but the majority of installations and in place upgrades I've done have gone pretty smooth even considering the insane amount of diverse software run on Windows 7 PCs. A far cry from OSX upgrades which break every damn thing in the known universe. Trying to think of the last time I've had somebody request I virtualize OSX and stream it....wait....never. That's because the iPhone does 99.99999% of what Mac desktop users do anyways; surf, FB, and play videos.
That said, I've done dozens migrations from magnetic spinners to SSD, and it's a piece of cake. If anything it's easier on PCs because there are more cloning
tools that support Volume Shadow Copy services which is light years more evolved than that time machine junk.
