Any port is still a remake, and no remake is exactly like the original. Emulation still is the best we have to try to get to the original experience.
The recomp/decomps have turned out to be the absolute best way to experience these games. QoL tweaks, the game runs like it should, and is vastly more accessible. On original HW some games (looking at you Oot) have memory spikes and slow downs which is obviously not an issue in these flavors. Emulators are just about always with some trade off - recomp/decomp absolutely don’t have that
Using the example of slow downs, some games even took that into account when being designed, e.g. Space Invaders and Shadow of the Colossus. While I don’t think those two are easy to come by in their original versions emulated (at least I don’t remember mentions about either), for those that would like to play through the original experience of a given game, emulation is the most guaranteed and accessible way to go. And though I can see the appeal of QoL changes, no change should disregard the original version of the game.
In my experience, the original is preserved in these kinds of projects. QoL, tweaks, and others are optional. While some games may have taken slow downs into account, many did not. These projects, I would say, are the definitive way to play. Stay true to the original, or get fed up with outdated control methodologies and toggle on QoL changes. Devs are very attune to how these games were originally designed and don’t forsake the original. As for emulators, you can still very much miss out on the intended way to play - think crt scanlines. And emulators are quite literally a hodgepodge of tweaks to make the games run. One of the reasons projects like this were born - because people wanted 100% accuracy
