Dropbox or Google disk? (Patreon)

Hi bunbuns! On my quest of finding the best viable option for sharing my Patreon rewards with y'all, I've considered switching to Google disk.

It's essentially the same format, and the same method of sharing the folders link into your Patreon inboxes. The only difference, which is a major pro for me, is that I can specify who can see the link by emails. Everyone who has a Patreon has an email, but not everyone who uses dropbox has a dropbox account. And so, only those who have their email added to the shared folder can view the content. Which means no one, even if they had the link, could see the folders contents unless they were pledged to my Patreon and had their emails added. (I will add the emails on my own, y'all dont need to worry about that!) Just make sure you're viewing the folder with the same email user registered to your Patreon account.

This could also make link/content accessibility easier by posting them underneath each post on Patreon w/o fearing the link, in addition to the post itself, being reposted somewhere else on a piracy website. (Though depending on how this might go, I may or may not implement this)
The transition would be smooth, and the google link would be given at the end of this month, so y'all would still have the link to the folders content in addition to the future ones all in one place (your inbox!)

And so, I ask, which do you prefer?
