No, these new ones blow them out of the water. Gyarados seems to better service against Iron Tail/Fire Blast sets for the added resistance, as they're weak to Stone Edge. Hariyama is great. Blaziken is good, its resistances more or less balance its frailness rather than cure it. Machamp is still #1.

Tyranitar raid counters list needs to be updated
How do the new Gyarados (with Waterfall) and Gen 3 Fighting-types (Blaziken/Hariyama) fare in Tyranitar raids? Are Primeape and the Hitmons still "Good Counters" in comparison?

Hariyama takes over the number two spot after Machamp as the best Tyranitar counter replacing Poliwrath. Still, Poliwrath is very useful, espacially against FB.
One a sidenote: For duoing Tyranitar if you first team faints Poliwrath will get autopicked for team number two in most cases. That's huge vs an autoselected Gyarados for example who will probably not be able to get off two HP or even one.
