my experience with mulching decks are that they dont allow you to cut very fast, the cut is nver very good (always straglers left behind)
We use side discharge and have discharge plates installed so we can close when travelling by flower beds etc.
If the grass is super tall and thick, it may require a second pass or a blower dispersing some clippings after cutting
