One of the reasons I would prefer turbo over SC is because with the SC, the engine needs to produce the extra power needed to run the SC, so I give up some extra wear and tear for a given HP target compared to a turbo. I've read differing views on how much power is being robbed, but that would be good info to have when comparing to turbo and even among the available SC options you've listed here.
