I just played the OG DOS version for years, that’d would be my recommendation.
Pioneer is indeed a love letter to the game, and is more modern, but I don’t think it’s a 1:1 comparison. I’m not 100% on that, however, as I don’t have as much time with Pioneer.
I think if you wanted the general gist of the gameplay, Pioneer would be fine. If you wanted the nitty and the gritty, run the original.
