I recently created a big playlist (7 hours plus)taking single tracks from about 140 albums for a party, using SB server on a PC, and it was not the slickest experience ever. Biggest problem is the delay in refreshing the web interface screen every time you click something.
I use a Transporter as my most audiophile source. The sluggishness of the web interface is a grumbling annoyance (and the front panel, whilst sufficient for me once the music's playing, is a poor place to make music selections). When I'm listening more casually, and the music isn't in high resolution, I sometimes switch to a Sonos ZP80 as the front end because the Sonos Desktop Controller is so much faster.
I won't consider Sooloos because
• I don't want the human interface stuck on the top of my hifi stack (or stuck on top of anything),
• (from this thread) the artwork issue is disappointing,
• I have the computer skills (competent but not expert) not to need turnkey ease of use,
• Sonos is sufficient, elegant, not too expensive and easy to use (good WAF) for the rest of the home, and
• I'd rather use the money for something else audiophile.
I think that probably covers many of the ideas in this thread.

Peter
