Depend on which plugin you use. See more info here

Slider Revolution, Layer slider plugins provide you 100% pure smooth drag & drop editor. but it doesn't include many functions. You can add different plugins for different purposes. Elementor plugin provides you the most of the site builder functions but its editor is not smoothly draggable. It is a block-based editor and very similar to Weebly editor. In the block-based editor, you can't put web elements wherever you want. Web elements are images, designs, buttons, text and 100's of different web functions.  The elements automatically settle inside the block. You can use both Slider Revolution & elementor at once, you can even use in a single page, but you can't merge and use it as a single editor and the same space of the page. Those are heavy plugins and your site may start to load very slowly. You should read -> How To Speed Up WordPress Website To Load Faster Than 97% Even 100 Plugins Activated [The Only 3 Techniques..!]
