MontrealMitch,
I have 2 zooms that are very nice, and 2 legendary primes. The primes are sharper. BUT, you will want to get a sense of how much sharper. I must say, a little bit sharper. I'ts not that big a deal unless you are just into getting the verrrrrry sharrrrpppeessst kind of image where the point is detail. Now, if you are into, for example portraits, you might want sharpness, but the poitn of your pictures might be form and lighting and softness of skin and composition, etc., in which case the difference in sharpness from zoom to prime, though real, is only marginal and may not be important for that use.
That said, a huge advantage of L primes, really, is that they are fast! You can hand hold the 35 1.4 or the 24 1.4 in available light indoors. But guess what... at wide open thoses magnificent lenses loose a little sharpness! So, the real advantage is big aperture, not sharpness. Aint that a kick in the head! (I want to get the 24 for the speed.) So, what I am getting at is that you should get to know the kind of pictures you want to make and see if you need to boost sharpness a tiny bit (a tiny deal), or boost speed by a few stops (a big deal) or boost flexibility, which means zoom (also a very big deal). As you get into it, you can always rent a prime you are interested in and see what it gives you. I must say, though, that in this comunity there is a lot of testing and fuss about ultimate sharpness, and the difference between the very good lenses and the legendary lenses is only a slight increment of sharpness. Speed is the big difference. Figure out what you like to shoot and what's important to you will emerge.
