Oh fair enough.
In my experience, vanilla openwrt is amazing but anytime you want to change anything it will take a while to reconfigure the whole thing.
That makes setting up a spontaneous guest network a little more time consuming for instance.
As long as what you need is more or less covered by glinet firmware then I would just stick with that.
Stable is often better for router firmware than bleeding edge in anycase unless there is something that you really need in the latest releases.
