We had both an Apple II+ and a Commodore 64 at school when I was about 10 and I just couldn't get into the C64- the slow disk drive (IIRC it's the bus that's the bottleneck) meant minutes of waiting for programs to start. While the Apple II+ would usually load things very quickly. In many ways the Apple was inferior (see the comparison chart in the linked article) but everything about it just felt "right" to me.
I had a similar experience when I got to college and my roommate and I compared our computers- I had a PC and he had an Amiga, and when he explained what it could do it was clearly superior, but it just didn't "feel right" to me.
