Using standard settings is 2 science labs still a good default opener?

Well as per title: I am always directly opening with 2 science buildings. And maybe even 4? Just to get that first tech out of the way? (Banking or experimentation).

This leaves me with few ships for scouting resources though, so am wondering: do you still think this is a good start? In a “netural” situation where you are not sure yet if you are landlocked or have aggressive neighbours.
