I loved the original back in the 90s. But hooboy, playing it now feels rough. Mouse look hadn't been invented yet (or at least, not popularized) and UI experimentation was still a thing. Remember, the OG System Shock released only a year after Doom (in which moving the mouse "up" moved your character forward.)

I love this reboot. It keeps so much of what made the original great and sands off a lot of the rough edges. I wish they'd made inventory management a little less clunky (it's a little too true to the original there), but that's really my only complaint.

If you like immersive sim games like Deus Ex or Dishonored, I highly recommend it.
