Hybrid turbos are the biggest waste of money I've seen, they just don't really make sense to me.
Garrett/Borgwarner/MHI design their turbos and put in a lot of effort to match the compressor, turbine, housing etc and then some hybrid turbo company bores a big hole in the turbine housing and messes it all up, or worse fits a bigger compressor whilst keeping the small turbine wheel. Most of the hybrids just have an uprated bearing, they then quote you can boost more, however they are far out of their designed efficiency range a likely nothing but a hot air pump.
When it's easy and cheap to do I'm not against hybrids, for example the K03S hybrid can work out quite well, however spending £500-£750 on one is just obscene. It's always going to be cheaper to get an adaptor made and use a different turbo that has the right compressor/turbine setup with appropriate housings.
