Well some guys like master xeon creator of Kitops etc have developed plugins that master boolean operations much better! In some cases though you had to move your cutters a wee bit to get clean results!
Well finally from 2.91-2.92 onwards the boolean developer branch is merged into the master branch ..and hurray we are getting nurbs style modeling for Blender!
A real big thing!
With Hardops Kitops...Meshmachine etc we are getting Sketchup like modeling into core Blender!
