uMatrix provides a more fine grained approach to blocking and has an interface to match this. uBlock's interface can be easier for a more coarse grained approach (see dynamic filtering, medium mode).

I never tried uMatrix. uBlock has the ability to block a particular set of links e.g. abc.com/min/* and whitelist some links within that set e.g. abc.com/min//.png. I think that's a fine grain approach. Can uMatrix do things like this?

Here is a quick tutorial showing what uMatrix can do https://github.com/gorhill/uMatrix/wiki/Very-bare-walkthroug.... As you can see, it gives you an easier way to have fine-grained control of each individual type of resource. It also allows you to configure third-party domain resources globally, or per domain. This allows you to do something like allow youtube embedding (js + xhr) on all websites at once.
