What is your opinion of the best platform to host the Adalo database?

Hello everyone!
For a complex app, what is your opinion of the best platforms to host the database through api in an app created in Adalo?
I know AWS S3 to host multimedia files, and I am currently trying to have the database in Xano, but do you know more options?
I see that there are others, but I don’t know the advantages or disadvantages, and I think it could be useful for the community to have some information from different platforms.
