Daikatana is an oldschool FPS that also tries some rudimentary RPG mechanics and is technically four games mashed with its own sets of weapons and enemies. It is as rough as it gets but Romero had the right ideas and much of what he envisioned in Daikatana ended up being the future of FPS

It has interesting ideas for its time, like NPC companions with voice lines, a leveling up system, and some creative weapons. Out of the 2 you mentioned, I guess it's still closer to Duke Nukem, but you can watch some gameplay videos or give it a try for $1 and see if you like it.
