I have listened to both extensively set up in the same system in the same room, one after the other.
The 3 is the better speaker if the room is large enough. If the room is not large enough, the 3 is a worse speaker. It comes down to the low end. Sopras are low end heavy generally and the 3s truly bring the bass. I didn’t have enough room in my living room at the time and it was way too boomy, and I enjoy bass. It was too much. Rear ported so 3s are best when they can be brought far off the wall.
So if you have a room that can absorb all that bass then get them. Otherwise go with the 2s, as I have, and enjoy. The 2s are some of the best speakers in the world.
