I actually like how each halloween movie has a different style mask. My top favorites are halloween 1978 halloween 6 the curse and halloween 5 revenge. I am curious to have others favorites and options please share 
Just my opinion.
H1/H2 The best hands down. Creepiness personified.
H4 Bad just tacky looking and an insult after seeing first mask.
H5 Worse. What the hell was going on with the hairline and stupidly long neck.
H6 Better. Started looking creepy and menacing instead of goofy like H4 and H5.
H20 Nice but didn’t like eyes showing constantly
H8 Liked certain angles but looked generally like a chimp with an afro
Rob Zombies Probably the second best mask to me, certain angles of the clean took me bk to H1 (original)
Zombies sequel Mask back down hill again, too much face exposed for me.
I couldnt have said it better myself! Right on Damian 
I LOVE the Captain Kirk-turned Shape mask from Halloween, ‘78 and Halloween II, ‘81! Of my favourite masks of all time, being 75’/76’ Kirks, the one used to create the Hero is my favourite out of them all! I loved the films, but honestly, if the mask were different I really don’t think I would be in, or at least as involved in, this hobby. I will admit to having an unhealthy obbsession with this mask. 
Extreme honesty ahead: Halloween III was a great film, but not a Myers-centric one so nothing to say there. But from Halloween 4 and onwards, I have absolutely zero interest in any of the masks. I know a lot of members here do, which I respect and that’s cool! They just don’t have that emotionless yet creepy mad/sad look to them.

I agree. The masks used for Myers after H2 make the rest of the films almost unwatchable. When I first saw the films in the 80’s I didn’t even notice the difference, but after looking for a quality replica, the other masks stand out like a sore thumb and just ruin the atmosphere.
