The benefit of the TRD unit is its compact easy to fit design.

But the rotrex is a centrigual supercharger, so it's still got a lag of sorts, does not provide off-idle boost, heats up VERY quickly and has high parasitic losses. Unless you're running mad boost, it's not THAT efficient IIRC. I know Koenigsegg use it on the CCS or CCX but there are heat issues, they needs large intercoolers
For std applications, roots provides the best off-idle response in low psi regions
