Ki vs KENTA was very good. I've always thought Richards vs KENTA was very underrated. It was a classic "underdog vs veteran" match up. Richards may have lost but he gained my respect.
Roderick Strong vs James Gibson from Unforgettable is one of the best matches in ROH history IMO. I'm not sure how this match is rated anything less than 5 stars. The things that took place after the match is what gets to me, Gibson crying while the fans chanted "Please Don't Go" & "Thank You Gibson" makes the match memorable.
Styles vs London will always be one of my personal favorites as it was the first ROH match I saw. I'm sure everyone remembers their first ROH viewing.
