I switched from iTeleport, which I used for more than 3 years. iTeleport has gotten unstable lately and Screens is so much more stable. But wait, there is more! With iTeleport I wasnt able to connect to my MacBook when it was in sleep mode, but Screens does every time I try it. This app is the best VNC app in the App Store.
