Testing uMatrix

I’m now trying to get used to the browser extension uMatrix. It’s a bit more advanced than uBlock Origin by the same developer and it let’s me select on which domains to allow or block cookies, css, scripts etc. I enabled the setting to block JavaScript by default, because I noticed that especially news sites sometimes load much faster (or at all) with JavaScript disabled and of course this reduces the amount of tracking a lot. Do you have experience with uMatrix and any tips on how to make the most use out of it?
