That really depends on what you are looking for, for VFR flying MSFS might be the best simulator on the market? From a visual perspective it sure is, from flight dynamics and system perspective I’m not too sure. For IFR flying FS2020 is definitely not the best out there, I made a list of items in need of fixing. Most of which is functionality already available in FSX or even FS9 from the start…
Simply put it this way, if you take the stunning visuals away, is there anything to be excited about? I would say no and for people interested in those amazing graphics that might be acceptable, other people are interested in a realistic flight simulator, low visibility take-offs and landings, accurate flight dynamics etc. for those people there are (at this moment) better options in my opinion.
