My favorite was sparks in NYC.
Locally, I am not a fan of the Chop House at all, but haven't been there in a few years. I think EB Green's is the best. Danny Sheehan's Steak House in Lockport is very good as well. The Colony in Silver Creek is a little known hidden gem, great food all around, but several very good steak options. I want to try Russell's, but have only done Happy Hours there. A friend swears by Riverstone Grill on Grand Island, it was on Man vs Food a while back, but haven't tried that one yet.
The steak houses in the casino's in Canada are pretty good as well. Lucky's at Casino Niagara and the 21 club in the Fallsview are both excellent steak options.
ok, I am hungry...
