My vote is also for the Salon2, but I think you'd be very happy with either.
The Salon2 is a speaker that I know very well because a friend owns a pair, and I get to hear them quite regularly, and driven by very high end SS amplification. I almost bought a pair myself, but ended up with B&W800 Diamonds.
Comments above are all valid IMO. The Salon's do an excellent job of creating well defined imaging with good depth of field. Perhaps not as expansive and speaker-less as some but still 8/10 in that dep't overall and better than the Sopra IMO.
The Salon's treble is also excellent, and really only limited by source and electronics although in some rooms the speakers may lack some air due to the directivity above 8kHz.
Salon mids are simply accurate, very detailed and in perfect balance.
Bass is extended and free from box coloration but you need a big powerful amp to get the max.
The Salon2 is a speaker that's difficult to criticise because it's so obviously free of many of the usual speaker vices. If I had to nominate an area of weakness it would probably be in the mid and upper bass where there's just a hint of congestion and a slight lack of coherence, but at this point it's really nit picking. Another point is that the bass may dominate in rooms that are too small or where the distance from room boundaries is insufficient. My friend has a large room but still needed to install traps on all corners to achieve near perfect balance.
FTR, Comparing them with my 800 di's is difficult because I've only heard them in different rooms and driven by different electronics. My impression though is that the Revel's are slightly more accurate, particularly from the mids and up. OTOH, the B&W's sound a bit bigger and bolder and deliver more dynamic impact and slam down low. I think the Revels win in terms of imaging specificity and scale, whereas the B&W's project everything a bit larger than life, but the B&W's imaging is more expansive, which may not be completely accurate but it's very inviting.
The new B&W800 D3's are a different beast and are a level above the Salon 2's but given the age difference as well as the rrp that's probably expected.
I'm definitely looking forward to hearing the Salon3, assuming there';s one in the pipeline.
