I use as zener shunt supply on the board I use to program my 2343s, because it's cheap, and easy.

I generally, will use a 7805-ish solution for most things, where I don't need efficiency.

Buck switchers where I do, and where the current demand is relatively high, and LDO linears where I need efficiency, and the current is low.

Engineering IS the art of compromise.
