Been running 3.10 since 3.9 went EOL. Had no problems with either release (albeit on my old hardware).
I would suppose that the point of LTS is that it's supported with security patches? So while problems, with regards to specific hardware, which were fixed in later releases, can persist, for many, it's usually a "safer" kernel to use than the latest stable. I would much rather run either a stable or an LTS kernel though than an EOL'd kernel such as 3.8 or 3.9. Thus my preference would be for 3.10.
