230 (or 240V) is better - that's why Britain chose it.
Neither 110V nor 240V are enough to kill you generally; both are enough, though, to throw you off a ladder if you get a belt working up there. No differences so far!
For a couple of kW, 110V needs double the current, 240V needs double the insulation, of the the other. But insulation is cheaper and less bulky than conductor material.
Switches, connectors, control gear is much easier and less lossy with 240V than 110V.
With AC, opening switch contacts extinguish their arcs just as readily with both voltages. No difference there!
A similar question might be: In cars, which is better, 6V or 12V? And again, for the same reasons, we standardised see on 12V.
