You could argue it's easier. The referee could make a marginal decision one way knowing full well it's the other way and VAR are stuck with the 'clear & obvious' get out. Same with Yellow Cards that should be Red - Ref gives it, VAR doesn't overturn it.
It's not only VAR decisions though. I've seen throw ins clearly come off opposing players and the ref/lino gives it the opposite way. You also have the disparity in applying the LOTG where opposition players can foul with impunity, yet ours are first foul yellow card. Then there is the application of the advantage rule and the ref blocking the passing lanes (as a particular referee used to do regularly with Spanish Dave). Then there is the subsequent stat padding towards the end of the game (booking a couple of opposition players for cheap fouls) to level things up when the match result sewn up. ALL theses things can affect the outcome of a game without VAR's intervention.
