No it isn't because several players are old and unfit for purpose on their position in a 4-3-3 or cannot last the length of a season playing there.
I've advocated for a 2-striker variant for a while, be it 3-man defense or a diamond, to restore the offensive balance and make it easier for us to score, but Zidane is vehement on sticking with 4-3-3 and playing the same thing over and over despite it never lasting more than a few weeks/months or being bailed out by set pieces. And we played actually really well with Jović out there with him vs Betis and another game.
If we want to be regular from open play, we need to either make sure Fede plays in a 4-3-3 every time, or switch to a wingerless system to ensure 2 strikers play off each other in the middle. Otherwise Benzema is too shit to work for opportunities in centre all season long
Issue as always is Zidane's insistence on always always slotting in Hazard/Vini at LW and balancing the help with Asensio or Vazquez at RW and fullbacks. Which is sad as qualities aren't there to sustain this. Especially from Benzema
