Here's my opinion without any credentials attached: * Free tier - essential * Documentation - essential * Stack overflow tag - desirable
How do you feel about a free tier vs a reasonable try before you buy?
Geocod.io has a free tier and we used it at work until we bought the full thing. Google Cloud has a trial and I activated it and then didn't use it so I didn't actually get to try it.
So not quite equivalent, I suppose, since the lock-in is tighter with free tier. You never put anything critical on trial but you do on free tier.
