Hatton may be more popular in Manchester, and perhaps in the UK. I reckon if you ask the average person from gen Z they won't even know Hatton, if they do, they'll know him as the guy who lost to Mayweather. Myself, outside of the Mayweather and Pacman fight, can only recall highlights of the Tsuzu fight. Since he retired, all I recall is drug problems, and autobiography, his son, and a few appearances on YouTube. But Bisping is more well known in the States, and around the world (especially South America and Mainland Europe), he even has a popular YouTube channel where he has likely branched out to non-fighting fans.
