Saying that, I have heard a bunch of people blowing engines using Royal Purple. But that's probably because they were pushing harder thinking their cars had royal purple and were invincible, similar to people that think stock Type R's are race cars and push their stock engines so sooo hard and blow them.

I don't think you'll notice much difference in different brands of oil in terms of performance if you change it often, but viscosities I find are extremely noticiable. The amount of engine response you lose from 10W-40 opposed to 5W-30 is amazing.
