The question is really if you want a setup that helps you right now in matches out one that magnifies your strength when you finally got the Playstyle you imagine.
For me being a heavy EJ I took a deliberately step back on terms of speed to strengthen what I can do currently, but once I have the technique and ingrained Playstyle that I plan to, I will switch to blades i already got that will suit the future Playstyle more. One might be arguing that it is possibly better to stick with one setup (even if it is too fast at first), because you will get to know if better.
I don't know the answer. Imagine these two scenarios:
Player Mike starts off with a Viscaria and double T05s in Max and plays for two years.
Player David uses a YSE with Vega Europe for a year, then changed rubber to Vega Pro for 6 Month and then finally "graduates" to a Viscaria with T05s. Who do you think will have mastered the setup better? Mike for sure, but David had probably learned better strokes and won much more games along that way, even though it will take him a bit of time to get accustomed to the new setup.
With a proper trainer pretty much every setup is possible. Without one you will probably better stick to something slow and start with it for 20 years never learn a real topspin, but that may suffice for some.
