Against it for every reason.
It costs more money to execute somebody than to imprison them for life, due to the amount of appeals necessary for death sentences. This is to try to avoid mistakes, which still happen. If they wanted to make it cheaper, they'd have to have fewer appeals, and make more mistakes. If they wanted to make it more efficient, and never accidentally kill anybody, it would cost much more money.
So the best way to have the fewest accidental executions and save the most money is to ban the death penalty altogether.
