Is the optical quality at all decent, compared with a prime? Not that you can buy good telephoto primes anymore....
Depends on your definition of “decent”. These work well for most general pics. If you have architectural lines or things like brick walls, you can sometimes see distortion (slightly curved line where things should be straight). All Superzooms of wide focal range exhibit degrees of this. I recent shit some pics that had column in the background, I had to correct the distortion by about 6% I photoshop.

The left side image above show barrel distortion, some lenses show pincushion distortion which pinches inward. For many subjects, this doesn't matter. I am not sure what programs correct for this other than photoshop. Lightroom probably does and other newer photo editing programs. I know that correction for this lens distortion is on my ancient Photoshop CS 5.5.
