I have had both, albeit each for a fairly brief time. Both performed nicely
enough that I didn't notice any weaknesses. The powerzoom certainly has
better build quality, but is much larger and heavier. The new 28-105 seems
to be considered an improvement over the silver non powerzoom (was it a
Tamron rebadged?) IF model. I recently replaced my 28-105 with a pair of F
series zooms, the 24-50 and the 70-210.

The new 28-105 tested in Pop Photo to be weaker than the 24-90 (which I've
used and regard as a good lens). This is reflected in the prices of the
two lenses.
The old PZ 28-105 is universally regarded as an exceptional lens. I have
two of them.
