Had same dilemma 2 yrs ago. Bought 08 GW and put a California kit on it with aquashields and it is a really nice trike. The leg room and sitting position isn't as comfy as the 09 RSV that thankfully I still have? I'm 6-3. I stopped by Hannigan and rode a triked RSV that I liked, but realized that GW power noticeably missing. Also during a short test drive of the RSV I missed the GW reverse feature.
Also I miss the 2 wheel handling of the Venture when on the trike. It's just that we can carry more and have a safer feeling when on a trike. If you go trike ride them all before buying.
Another thing is the front trike tire. I have had a Michelin Pilot that gives a harsh front end feel and also a Bridgestone Battax . Both are hard compound tires and they convinced me that my next front tire will be a regular motorcycle tire with softer compound and won't transfer every little road bump to the grips.
I think the GW has a good sound system but no CB. I'm happy to have the RSV and have been tempted to sell the trike. Still can't say that I'd trike the Yamaha just cause I like the motorcycle feel. Sorry to ramble on.
If you are in the KC area give me a call or call anyway if you'd like to talk bikes vrs trikes.
