Mein Auto: rescued bmw's
both are great for decarboning the combustion chambers, and removing intake deposits. i have used both via a vacuum bleed and actual shop set ups (when i was a tech).

as for engine sludge buildup in the crankcase, it may remove the buildup, but nothing will repair the damage caused from the neglect of infrequent oil changes/abuse. once the oil rings are gone, it's teardown time.
