>>14317512Literally almost anything in his NJPW tenure from 2016-2019 (2019 he only had his WK13 title defense against Tana). My first Omega match I ever saw was Omega-Jericho 1 at Wrestle Kingdom 12 and imo that’s one I personally like a lot. Imo Omega really “arrived” at the G1 Climax 2016 when he became the first non Japanese to win the tournament.
Tanahashi - WK13
Naito - G1 26 seminfinals
Naito - G1 27 finals
White - New Beginning 2018
Ishii - G1 28
Ishii - Destruction 2018
Ibushi - G1 28 semifinals
These are all pretty good Omega matches off the top of my head aside from Jericho 1.
