There's not much price difference between the 150 and 200 amp service.
So you might as well get the 200.


But a 150A can be run (with great difficulty) in a 1 1/4 conduit if
that's what he's got already. (Use 1 1/2 or 2" if you gotta run new
service conduit anyway)

And the wire is a lot cheaper for 150A. And the panel is a little bit
smaller and might be easier to fit in the existing space.

He needs to do the load calculations and see what size he really needs
though, then probably go one size larger.
