+1 for VANOS (M50tu). The VANOS engine produces torque sooner and for an overall longer duration. I think overall HP rating is about the same which makes things a little misleading. The VANOS is a good thing and BMW is still using it in their modern engines.
There are lots of claims out there that the M50 (non VANOS) is a stronger motor since it does have forged connecting rods and dual valve springs. People claim that the block casting is thicker too and can therefore be bored out to ~86mm (in case you wanted to make a 3.0L motor out of it with the addition of a S50 internals). The camshafts have a different grind than the M50tu.
