I prefer Halloween 1, 2 and H20
... as an unofficial but definitive "Halloween" trilogy, as opposed to all of them, the two Rob Zombie films or the first film and "Halloween" (2018).
Halloween 1 - kicks off the Laurie Strode vs Michael Myers story
Halloween 2 - wraps up Loomis' role in the films
Halloween H20 - concludes the storyline between a grown-up Laurie and Michael
I guess there are so many films in this series now (two different "timelines", one alternate "universe", and however you want to view "Halloween 3") that you can essentially mix-and-match them into your own favourite version of the storyline...
