MongoDB vs Amazon DynamoDB
Ten of twelve models named MongoDB first on the direct prompt; zero named Amazon DynamoDB. Both were named by all twelve models and MongoDB carries 69 labels and Amazon DynamoDB 51, so the shares are not directly comparable.

The direct prompt
The plain question, one answer per model, grouped by where MongoDB and Amazon DynamoDB stood in it.
