It has been my experience that performance differences are so small that unless you have a specialized, monetized, task the differences are irrelevant. Those tasks won't typically be run on a $20 SBC. For example the spread between compiling a modest program on a modest PC might be 75 seconds on Ubuntu and 72 seconds on Clear. So you save 4% on compilations, minutes if you do hundreds of compilations per day. But boy oh boy it is much easier to find an article on how to accomplish an administration task for Ubuntu than it is Clear.
