Greg,
I think people are not liking the Workingman 15 model, which has the 15 speaker + tweeter, and a semi-parametric mid. I haven't actually played one, but generally speaking it doesn't surprise me that a 15 speaker sounds a little honky.
Then again the SWR tone controls let you do a lot of adjusting, and you can soon adjust your way out of a decent tone - add to that what you can adjust on your Alembic, and you can be lost in space. The big problem with SWR amps is that people often think that the Aural Enhancer is a boost/cut control, while it's a boost-only control, and it can really mess up your tone.
By the way, I've heard horrible sounds coming out of Eden rigs ... It's not what the amp can do for you, it's what you can do with the amp.
I love the Workingman 12 model. If you're looking for a pleasant tone, start with all the controls in neutral, and the Aural Enhancer turned down completely, and work from there. This combo will fill small-sized jazz clubs nicely, provided that other amplified sounds are not very loud.
I also played the Baby Baby Blue in a shop - a 160W 10 + tweeter pro-level amp, with a multi-band parametric eq. Even with an active Fender Jazz, and the controls in neutral, it gave out a very sweet tone with plenty of highs (tube pre-amp). But I got the feeling that it didn't push a lot of air, even with the master volume at 5. Perhaps an extension cabinet would help there. It's about 10 pounds lighter than the Workingman 12, but unfortunately also more expensive.
Not sure what will happen to SWR now that they've been bought by Fender ... Check out old stock in shops.
