Disappointed by the LG Nexus 5X specs and price ... is the LG G4 still worth buying?

As the title says, I am really disappointed by the N5X price in Europe compared to the specs. Is the LG G4 still worth buying it?
Is the LG overlay acceptable? (This is the only thing which really holds me off buying the G4 at the moment, because I really love stock Android)
Is LG offering some stock Android experience? (like HTC did)
How fast the software updates get released?
