My personal best time for the Puyo Puyo Tetris 150 lines marathon on Nintendo Switch as of 29 April 2019 -- 5:20.21. This time can easily get a lot lower if I get more fluency when playing, not stopping that often to think a move.

Sorry for the poor video quality, this was the only way to record the run I had and I'm a bit sick at the time of doing this, sorry about the background noises too.
