Apart from the obvious ones there's some underrated ones i really enjoy. Daniel Zaragoza vs Paul Banke Dennis Andries vs Jeff Harding
I hate to be picky but Vazquez/Marquez Pacquiao/Marquez had 4 fights, but i tend not to count the 4th fight of Vazquez vs Marquez and just count it as a trilogy.
Fantastic pick with Zaragoza vs Banke. Top 5 trilogy when it comes to sheer entertainment. That second fight was something special.
One of my favorites as well. I always recommend anyone to watch Zaragoza vs Banke, especially the second one which is one of the most brutal fights.
I forgot they even had a trilogy TBH, the only fight i really remember about their trilogy was the 1st fight which was very good. But i remember being disappointed by the ending.
