Saving an array to a cloud account

Hi all,

I know this has been discussed before but I am still finding it hard to find a clear answer.

I would like the user to use their email to 'create an account' (either on Google or FB). Once this is done, all their data is saved on an array that is associated with that account and which is located on 'the cloud'. This array will be sporadically updated while the player is playing.

So now, I have been reading many of the old posts and I have found these two options:

1. constructfirebase.com/plans-pricing

2. constructcollection.com/construct-playfab-api

...

So my question is, which is the best choice for my purposes? Or, is there a better choice?

I know zero JS, but I feel comfortable copy/pasting code if that is needed, but would prefer to use the C3 native choices. I want to keep it as simple (and cheap) as possible.

Just found blackhornets PlayFab tutorial. Thanks for that!!

So maybe this is the answer to my question? It's free and looks doable. I think it covers both player accounts and cloud saving. But perhaps Chandori's is easier for a beginner? IDK

So now the question is, Which service is better for my needs? Firebase or PlayFab? Again, i'm looking for ease of use and cheap. I'm not really concerned with having a whole suite of utilities.
