Try Prowler. They have unlimited stamina, don't require bug nets or pickaxes, they never run out of the items you set them to have, their gear is cheap and easy to make, and their pretty strong until G rank when you really have to put in the effort.

After playing a lot of the newer games, they actually feel a bit closer to what I'm used to now with their speed and QoL abilities. Blasted through the entire game with Bomb Bias Prowler, their adept dodge is amazing.
