I think it's great to embrace different hardware in your collection if you're looking to branch out. I love variety. In the case of my Bal bags I'm an RH girl through and through, although I could be tempted to purchase a smaller accessory (coin purse, for example) in SGH.
I used to be a RH girl, only RH and mostly Cities. But then the GH started to grow on me and when I got my fist GH, an Anthra GSH Envelope Clutch, I realized that I really liked GH. So I got a Tempete GSH City and I was hooked! Sadly for my wallet, lol I still have most RH bags, but I like to vary. The RHs are more neutral and sometimes I'm in the mood for that and sometimes for a little more bling bling!
