From my personal view:
The 4.4.x series is “still rather fresh”. There were new features an reworked code introduced, and the bug fixing has not yet (4.4.1) sufficiently advanced.
You may, however, comb through the 4.4 release notes for features you urgently are longing for, and which might be a reason to go some risk living with an unfixed bug.
With regard to 4.2.8 I never understood for what reason it was offered as the standard “still” version for a long time. It contained a bug which, though not of great importance for every user, was reason enough to introduce an extra release (3.3.4) to get rid of it. I also would recommend to treat 4.3.6 as the best available STILL version.
Editing with respect to the comment by @Beizerno -
Again from my personal point of view: Don’t take it too serious. If you are not interested in details and in giving feedback simply shift to a new “branch of the second digit” when it comes near the end of its “lifecycle”. If you are missing features, however, visit the release notes for the series of releases to come and decide then whether or not its features are worth taking a risk as I told above. Even if you don’t like to go into details yourself, you will - as any human - at least have to decide of your own whom to ask for advice. Follow the TDF, follow me, follow someone else, overcome your dislike to worry about details … It’s your turn. Who should decide when time has come to shift to the next version of your car or to another whisky brand?
