I feel you, but one problem is that it is often hard to rank libraries best to worst. 20 may be a bit much, but still -- one library may be the most popular, another fastest, another correctly handles this one specific unusual case, another works well with large objects, another has more convenient interface for your case, etc.

What would be ideal is if there was useful information about such things available right on the aggregator site -- Amazon style reviews wouldn't be too useful here tbh, ideally one would like to see multiple comparisons from people like you who tried or at least looked at a few of them.
