physicall and operationally, the thing is an absolute tank. Still hashing away after all these years without hesitation. But economically (even as a space heater) s19’s or even s17’s can be had for just a few hundred bucks and make exponentially more sense..

the only advantage to the s9 is the direct plug in to 120v with no modifications, but there are people solving that problem for the newer gen miners already and I expect those solutions to get more popular / more user friendly as time goes by.
