beside my experience that gps + glanoss works better than gps + galilieo at the moment, why not installing the current beta?
the current beta is not worse than the latest "stable" firmware and the "stable" firmwares are betas themselves - just the way they are installed is different (and that they are not called beta officially).
Not entirely true, betas bring in features that can be in various stages of completeness and can perform unexpectedly or not at all. Only when major issues are released, the beta is released as stable.
Nothing to get excited about. It's just another alternative and with current HW the accuracy is comparable to GPS. Because satellite availability is still low it may well be that GPS+GNSS gives a better coverage.
I'm keeping it on for now although still seems it's kind of mixed bag. Sometimes slightly better, sometimes even worse than before.
