Best advice I was ever given was find something that suits you and stop worrying about it. Hence been using same guitars with same gauges for 30 years.

There are so many variables including the guitar, the action and whether you play with thumb/finger picks that there are no rules about 'best' gauges other than use higher action/ heavier strings for slide (Open G is the classic slide tuning). You can find a compromise for regular playing and slide but two guitars set up differently is much better.

F.w.i.w. I never found any problem tuning my regular gauge set 12-16-24-34-54 for normal or Open G. My slide instrument stays in G and has 14-18-26-36-46-56. As Ry Cooder pointed out in an interview years ago, playing in D (out of 7th fret) in G tuning has the funkiest thing going. And G min is a great variant too - D G D G Bb D
