What backlink API provider to choose?

We've run a huge data comparison study to see which solution provides deeper backlink analytics and the best value for money.
1) The biggest comparison to date. For this study, we'd purchased the API keys from each of the compared providers ($6,200 worth in total) and tested their data on 1 million web's largest domains.
2) Data transparency. The raw data files are available for anyone to re-run the comparison. To verify that the data hasn't been modified in any way, you can reach out to the mentioned companies and purchase the similar stats from them.
