For me I think the choice was simple. I could get a used X37 with a manifold and large inlet for $1000 picked up. A new X47 (Too new to find them used anywhere) would be $1,800 without shipping with the stock turbo inlet and stock wastegate. Fitted with both the larger inlet and new wastegate puts the X47 over $2,295 + shipping. So even with porting/polishing ($350 from SS, highly recommended) it was still nearly a 1,000 dollar delta between the two turbos for about 10whp. Is 10whp worth $1,000? To me it was not. Chances are the turbos will feel similar and they clearly perform about the same.
No hybrid turbo is going to make the car into a gaint killer. But they all make the car feel like it should have come from the factory. No longer do you get a single punch of power down ridiculously low, now the turbo hits hard at 2,800-3,000 RPM and says in boost all the way to redline. The X47 wasn't worth it for me but it all depends on the deal you can get and the build you want to do.
