Rene Ritchie's pick of the week on MacBreak Weekly episode 398 is version 3 of Screens VNC for Mac, which was just released by Edovia. This app gives you remote access and Screen Sharing to other Mac, Windows, or Linux computers. There are plenty of VNC clients available, but very few of them have a Mac-like interface like Screens does.
The new version of Screens VNC is faster than its predecessor, and is optimized for OS X Mavericks. It has pasteboard support, so you can easily copy text and images from the remote computer. It's also easy to connect to recently used computers by clicking and holding on the Screens icon in the dock. Screens VNC for Mac by Edovia is $34.99. They also have an iOS 7 version of the app for $19.99.
