I was always a PowerMac guy, partly for the performance over the older generations of iMacs and partly for the Cinema Display. I go all the way back to the "El Captitan" Blue & White G3. I upgraded about every third model or so. My kids had the original Bondi Blue iMac, then the "Luxo" iMac. I was about to pull the trigger on the PowerMac G5 when a friend whispered in my ear to hold off and consider attending the WWDC that summer. It was 2005. Sure enough, Jobs announced the switch to Intel processors and everything changed. Suddenly the iMac went from an entry level computer to a serious professional grade computer for all but the most hardcore users. I was NOT a hardcore graphics pro or anything like that. More of an "inspired amateur" so the iMac became the obvious choice for me. More computing power than I needed, space-saving all in one design, and a gorgeous screen. I bought my first Intel iMac almost grudgingly, unable to shake the feeling that I was giving up so much - the ability to upgrade components, the extra power of the Mac Pro/PowerMac, and maybe the ability to say I was a "serous Mac user". I still had the mindset that the iMac was a novice computer. That's the way Apple marketed them initially.
Now, considering everything I can do on my iMac that I couldn't do on my older PowerMacs I know better. You don't have to sacrifice performance for the convenience and clean industrial design.
