I have been using Debian stable for the last few months, but it has not always been a blast. Often times, I have had to look for backports, and in some cases, I have been presented with only two options: 1) make a backport (maybe not something I want to do in the moment because of time) or 2) upgrade to Debian testing.
The Debian Installer team has just announced that the first Alpha build of the Debian 8 "Jessie" version is now available for download and testing. The Debian developers are taking their time with each new version of Debian and they are known for releasing very stable builds. This can only be done if all the kinks have been ironed out well before any release.
