What is your preferred File Format to download? (Patreon)

Hi guys, I've been uploading a lot of files as of late in multiple formats. So I wanted to gauge what files you prefer to download and access my art files in. I know not everyone has SAI2 so I started uploading PSDs of my files as well.

If you want to leave a comment regarding your choice, that'd be good too. I'd also love to know what some of you do with these files I upload.
