Just strictly speaking from reliability perspective, the M256 in the 450 will be more reliable, it was on the market for longer than the M254 in the 350. Then there is also the fact that the six cylinder doesn't have to work as hard as the four cylinder to complete the same task.

M254 is a troubled engine (cylinder head failures) and it is descended from a long line of troubled MB four-bangers. Looks like you made the right choice to stay away from the M254.
