I've been through Betamax & VHS - pan & scan / widescreen 4:3 releases, Laserdisc editions, DVDs, Blu-ray and now 4K UHD HDR Blu-ray.
My format of choice for ALIEN (1979 Theatrical Cut) is the 2019 4K UHD HDR Blu-ray 40th Anniversary Edition.
My format of choice for ALIEN (2003/10 Director's Cut) is the 2010 Anthology Blu-ray release.
