Thank you for saying that, I agree!

Short answer: Yes.
Less short answer: With the odd exception (12-24mm, I'm lookin' at you) primes still deliver superior IQ. Plus, big apertures! I love all things fast, and f/2.8 is not that. Good luck trying to pry my 85mm f/1.4 out of my cold, dead hands.
The 12-24 I think is a tad soft and I wish I'd gotten the Tokina version as I hear it's IQ is a bit better.
I started photography using the kit lens, and I have used a few friends nicer zooms like the 17-55 as well.
However, I have fallen in love with my 35 1.8. I find the lack of zoom limits my speed in some ways but overall I feel it has made me a much better photographer.
I like the shallow dof (and probably overuse it) but I also just like zooming with my feet.. I didn't think it would be true but primes really do force you to think more about composition. I feel like with a zoom I can take a snapshot of anything, but with the 35 1.8 I have to think a hell of a lot more before I really "make" my picture.
I want to try an 85mm prime sometime and see how it feels!
Primes tend to do that and I've noticed this too even with my 300mm prime. I really have to plan those shots even earlier than with my zooms.
