I think Tony relies on being very unorthodox and puts people on the defensive with crazy kicks, clinch/td attempts and that allows him to exploit some nice punches he has. Pure boxing, I think he's behind a few guys. It's like with GSP. He has good boxing, but it works because of the other threats. 1. Conor. Say what you want about him, but everybody knows what he's going to do and nobody can stop it. 2. Gustafsson. Although not defensively as solid as he should be, he is one of the few guys that has good footwork and can trap people, coupled with a good jab and complete punching arsenal, I think he should be up there. 3. Frankie. Good clean technique, limited power but great volume and in the past years improved defence as well. 4. Cody. Necktats has good speed and power, and some nice movement as well. 5. Whittaker. Best left hook in the house, and some nice footwork as well. I feel he could improve of his variety though This is not a ranking, just 5 guys I feel have very good boxing in the UFC.
