My collection's as follows:
Alien (6 Disc) Anthology 2010
Prometheus (3 Disc) Collector's Edition
Prometheus 4K Blu-ray
Alien Covenant 4K Blu-ray
Alien 40th Anniversary 4K Blu-ray
And that's what I honestly recommend.
Yep. That's absolutely the best way to get each movie in its highest currently available quality while also retaining the Blu-ray era's bonus features as well.
Crossing my fingers and hoping for 4K releases of Aliens
, Alien 3
, and Alien: Resurrection
. But not quite holding my breath at the moment. Aliens
has the best chance of happening out of the three, but hopefully the restoration isn't botched Terminator 2: Judgement Day
