TGR compared to Proraso/SCS

[Obsessed]

I'm wondering if anyone can compare the performance of The Gentlemen's Refinery ASB, on the one hand, and either Proraso ASB or SCS ASM on the other. Whatever you think is noteworthy. Obviously, TGR is much more expensive; I'm wondering whether it's worth buying in addition to the other two, which are both excellent at a lower cost.

Thanks.
