Depends on what you're looking for.  linux-stable is by definition always
behind Linus's tree, and has backported patches applied to it.

In particular, note that only a subset of patches that go into Linus's tree end
up also applied to linux-stable.  In fact, in some cases a distro kernel has more
fixes applied to it than a later linux-stable - a vendor 4.14.5 can have more
vendor-backported fixes than a stock 4.14.8 kernel.

So if you're building your own kernel from a git tree, your first question should
be "*why* am I building a kernel instead of using the distro kernel?", and decide
what git tree based on that.
