It's not the best way. It's a really cool and technically interesting way. But embedding the model with the executable is terrible for anything beyond a demo. The best way would be just running llama.cpp (what llamafile uses) and loading external models. I get that compiling is too difficult for some people and llamafiles are great for them. Maybe even the best for them.
But it's far from best for people that actually want to explore LLM and play.
