How does Pale Moon compare to other browsers?

This is a very subjective question, and there is no single answer to it.

Short answer: YMMV (Your Mileage May Vary)

It all depends on what you are looking for in a browser to choose which one would work best for you. In general, Pale Moon aims to be full-featured, but without compromise to efficient resource/hardware use. It doesn't necessarily aim to be a lightweight browser, but seems to achieve that goal in some circumstances as a side effect.
Overall, comparison between browsers would put Pale Moon in a similar position to its sibling Firefox, albeit with more speed and efficiency (and according to quite a number of users: more stability).

Synthetic benchmarks aren't the end-all of things, either, so it's difficult to obtain unbiased comparisons between different browsers.
