1080p

I'm interested in acquiring high quality(fidelity) adult content but I'm unsure about which route I should go. For the companies that don't offer Blu-ray and only DVD format physical copies. I'm wondering if it's better to get a membership and download from their website to get full 1080p or 4K...
