Would four Admiral-class or four G3 battlecruisers be the better force?
Short answerFour G3s, because they are the more sensible overall design despite their poor gun arcs.
NotesFor equal four-ship groups, the G3s are preferred over the Admirals. The later design offers the stronger overall engineering and protection package. That choice remains qualified by the G3 turret arrangement and its poor fighting arcs. The stronger class still carries a major operational flaw.
