Are charge pumps better than boost converters since charge pumps do not use inductors?
Boost converters can be efficient at a continuous range of voltage ratios.
Charge pumps work best at fixed ratios. and for ratios other than (approximately) 2:1 or -1:1 they become increasingly complex.

I've got a 2W boost converter (5V to 12V) here that has an inductor about as big as a tic-tac, I've never seen a 2W charge pump.
