I run a wallet in Cake. It's not my primary wallet, but I still use it. From a usability standpoint, Cake is really nice. It's well designed, and simple. I haven't tried creating a multi-sig wallet with it, but it looks like it has the capability. The Silent Payment feature is really nice, and they're one of the only wallets that supports that. Plus, it's cool to have your XMR and BTC wallets all under one roof. It's definitely one of the wallets I'd recommend to new bitcoiners.
