Would life be simpler if both were the same size?

I suppose if you favour pushfit then it would, however it would be a
right PITA if you were using solvent and kept finding joints that would
not weld.

The problem comes when you have to join pushfit waste and solvent weld
waste. IIRC the only way to do that is with a compression joint and some
of those have ridiculously big nuts, which can't fit in tight spaces
under floorboards and other awkward places.

Fittings are made for the coversion I've seen them in the Warehouse B&Qs

BES have universal pushfit couplers that will mate with either:
