That's a tough one. The new designs are significantly new and improved, and rumor has it that the 3.6 is slated to become the 3.7 in the forseeable future. However, the 3.6 is probably a very good value, and is worth considering from that standpoint.
I have not heard the 3.6, but I had the 2.3 and now the 7.2. I would personally probably go with the newer design. If you have a large room or need the extra extension into the lower frequencies, then the 3.6 might be the ticket. It's just that if I got the 3.6, I would probably be always haunted about trading up to the newer designs.
Also, have you considered the 6, or is this out of budget? The 6 is very nice and leaves nothing to be desired for the future.
