Internet Explorer 11 is good and pretty fast, however I found Edge even more faster, and the new features implemented makes it more complete and comfortable than IE.
However Edge, compared to IE, doesn't have extensions support yet. It's still in development.
So I may suggest you to stick to Edge for speed, but for things like AdBlockers I would avoid IE and go for a different browser, I recommend Opera in this case.
Before Windows 10 I used to use (sorry for the repetition) both Opera and IE, as Opera as main browser, and IE for secondary actions and when I needed a faster boot and loading speed.
Now I use Edge and Opera, where Edge is my main browser.
