This would be useful because features aren't the only thing to compare. These are some sections I propose:
Documentation
In-line (like ESDoc, YARD, JavaDoc etc.)
Explicit (method documentation explicitly written out, like discord.js has)
Tutorials
maybe a value that rates the coverage of the documentation
Examples
Implementation details
Are tokens cached?
Is it async/threaded? If yes, how much and what parts?
...
Extensions (I guess these are technically features, but unrelated to API support)
Command parsing
Temporary event handlers added on-the-fly, I call these "awaits", discord.js has "awaitResponse"
(others)
Security
Does REST use HTTPS?
Is wss used?
Are cached tokens encrypted? If yes, how strong?
Voice encryption?
A field that displays the current amount of GitHub stars, using one of these fancy always-up-to-date image providers
Please propose other sections here you might find useful or necessary!
