Native means smaller file sizes…but there are no sequence settings for native. You’d have to edit in a ProRes timeline. Drawback is that you will have a green render bar and the quality will be lower until you render, but you save space on the drive. ProRes is better, there are settings for that, but it eats up more drive space.
Give and take. I prefer to import as ProRes Proxy if I have a large project, then media manage the project and reimport only the clips used in the cut at full ProRes HQ. Or if you have the space and it is a smaller project, bring things in ProRes from the start.
