What Pokemon Rom hack is best for me?

I lived Red and Blue as a kid. I think I played Gold on an emulator back in the day.

I really loved the challenge I had playing Red as a kid. I liked getting through an area with just a few hp left.

I never got hardcore into the newer games and have been so disappointed with how easy and hand holding the newer games have been.

I would like to play a romhack. Can someone make a recommendation for me?
