What about the "L" quality are you thinking of specifically? Glass? Build quality? USM?
The Tamron 17-50mm has great optics, but only "good" build quality and no ultra-sonic motor.

Just be like everyone else and get the Tamron 17-50. Its my primary lens and love it, especially the constant f/2.8! Its nice and wide angle, excellent glass, and the petal lens hood is included for $450 new from B&H.
The Canon 17-85 suffers horribly from CA and the pincushion effect.

what is your take on the
Canon EF 17-40mm f/4L ?
The aperture seems a bit slow but looking back to my pictures from my 18 - 55 kit lens 90% of my pictures are take an f/8 ish

SLRGear (you should really check that site out...) says:
Chromatic aberration is moderate at 17mm, very low at 24 and 31mm, and then rises again for large apertures at 40mm. Vignetting is remarkably low, less than 1/4 EV at all apertures and focal lengths, almost non-existent at apertures of f/8 and higher, at all focal lengths 24mm and above. Geometric distortion is a little higher, with about 0.7% barrel distortion at 17mm, although this decreases to only 0.1% pincushion at 40mm. (Again, note that these figures are when used with an APS-C size sensor: Full frame results would doubtless be worse.)
