I have nothing but praise for the SG, I use mine for everything, will say though after about 300 miles on the highway my butts getting sore but thats my fault for running a badlander seat on a long cruise.
If I didn't ride two up so much, the SG would be my weapon of choice. My father has one and I ride it every chance I get. Probably my favorite bike I've ever ridden, and that's quite a few. I wouldn't hesitate to get one for around town and touring. I think it does both quite well.
I love the SG but also a heritage is a great bike for cruising around and has the bags for ur sh**. Feel is different for sure but for around town riding I would say the heritage would be a great bike also. To each his own
