One reason one might want this is because of the hacker spirit. It seems more interesting and impressive to do what something was deliberately designed to not do.
Another reason is that Apple’s hardware tend to be very high quality. For example, on JavaScript benchmarks (which you may or may not consider to be a good proxy for general/single threaded performance), an iPhone7 performs comparably to the current latest Android phones. Also spare parts or replacements are easy to come by.
I’m quite unconvinced that the boot loader exploit demonstrates that the platform is so insecure that you shouldn’t use it. If you want to run a different operating system on a typical android device you would either not need to circumvent such security measures (which doesn’t mean that they exist or work) or you would use some exploit that didn’t get such wide press.
"Ahead" isn't quite the right word. Making a large die area high performance ARM isn't hard. Its just very expensive, and only Apple has both the volume and margins to justify it.
