I would argue that ESFM has better range and bass response in that second video but unfortunately it was recorded on a poorly filtered cheap card hence the floor noise.
Check this out for how different Genuine YaMaha OPL3 can sound on different cards with different filtering.
https://youtu.be/_ibdIm-ZBB4Last card is a properly filtered ESS Audiodrive with great warm and punchy FM Synthesis, it sounds closer to the SB Pro than some of the SB16s with no bass response whatsoever IMO.
Also check out the Crystal FM. People diss Crystal for not being genuine OPL3 but can you honestly tell me it is worse? It is different but still very pleasant. That sweet drumset..
Long story short, OPL3 is not the holy grail of FM music.
