Boring name, but I don't really get excited about the OS names. Mavericks and Yosemite were equally boring to me and I always have to think about which ones they are (numerically).
That said, anything that uses less CPU/GPU and is far more efficient while doing so, has got my vote. I haven't suffered many of the plagues people keep complaining about in Yosemite, but I'll never turn down refinements and optimizations.
