If by internally wastegated you mean like a vnt, or vanes that vary their angle in the exhaust side I would go with the Borg warner

From tests I've read the bw aren't as magical as people were hoping. Not to mention price for the turbos.

No he means exactly that: the turbo has a wastegate built into the turbine housing.

You're talking about a variable geometry turbo, which neither of these are.
