They can't be compared to each other because they use different subgenres, and they need to because they can't repeat what happened in the previous movie.
The first movie uses horror based on suspense: the creature appears fully only at the end.
The second movie could not repeat that for obvious reasons so it uses action, and involving more than one alien.
The third movie couldn't do both so it uses a procedural--how to capture and kill the creature--with one subplot likely intended to end the franchise.
Similar happened to the fourth movie, which pits several human groups against each other amidst multiple aliens, with political intrigue as a context.
Also, the prequels, which have cosmology as a pretext and then rehash stories, appearances, etc., from the previous movies to reboot the franchise, i.e., given the assumption that most young viewers had never seen the older movies, then they can focus on these while franchise owners can also re-imagine, remake, etc., the older movies.
Meanwhile, the new movie might use teens with drama, etc., and the TV show focusing on human groups contending with each other while facing AI, both bioweapons and mechs, and the aliens serving as a background.
