I'm relatively new to BTC and i like the Exodus wallet a lot because it has simple buttons and functions. It will hold REP, BTC, Dash, Doge, GNT, and LTC and they are soon to add DCR. With a few clicks you can trade any of these on ShapeShift right within the wallet. There's fees for trading, but that's okay for myself because I don't have the time or patience to do it otherwise.
