It seemed was a time in the history of OS X (up through Snow Leopard) where the reverse was true, and it's certainly not true that the OS must become less efficient with each iteration.
Why are you introducing an irrelevant tangent into the conversation? I have an old Dell in my closest that has Linux on it. But once again, that's irrelevant to this conversation.
I currently have two apple laptops, an old macbook that came with Tiger and use it to test beta versions of OSX. It's running El Capitan right now but is almost unusable.
My main computer is a rMBP that came with Lion. It worked better (faster, snappier) with Mountain Lion than it does with El Capitan.
There was just one dud of an OS in there (Mavericks? I think) where the machine would just bog down over the week and I had to reboot it every 2 weeks just to regain performance. That was improved with the next release, and now on El Cap I only ever reboot for security updates (two months or so of uptime)
OS X does tend to get more RAM-hungry with each version though, so I recommend everyone to max out the RAM when they can.
I dual boot Windows 10 even Windows 8/8.1 my 17 inch Macbook Pro 8,3 even with 2.3GHz i7 CPU 8GB RAM and 512 SSD is like a hair dryer fans on constantly never stopping but not when using OS X.
It's fine with Yosemite 10.10.5 but I am hesitant to upgrade to El Capitan 10.11.6 anytime soon. I may even downgrade to Win 7 if I can but I hear MS is insistent on people using Win 10 even if they will not push it out you can still get it.
The computer you're running is 6 years old. Apple doesn't sell it anymore. It's also possible to replace the HDD with a new SSD.

Even so, most people would use your 2010 iMac with much satisfaction.

Apple sells expensive computers. Customers are not buying cutting edge hardware, they're buying middling hardware that is designed to work with the specific operating system.
