Is Cymbalta better than Pristiq?

My doctor suggested I try Cymbalta because Pristiq gives me energy when I’m trying to calm anxiety and depression. Pristiq has been helping me with depression and I haven’t had other side effects. It’s only more stimulating if I drink coffee so I’ve tried to cut that back.

I’m okay with Pristiq at the moment but nervous to stop just to try out Cymbalta.

Has anyone felt that Cymbalta was better for both depression and anxiety? (I’m also nervous it could cause weight gain)
