If it fits, and it breathes, it's basically fine. This from someone who's still diving his "rookie" gear of almost 18 years ago (mostly Scubapro).
The car analogy only gets us so far. I drive a stick-shift Corolla (the stick makes it "interesting"). It's fine. There are sophisticated cars costing ten times as much, and worth it for those who want those features. But ten times the scuba gear price doesn't get you a ten times more wonderful scuba experience (I'm talking about basic open-circuit gear here, not rebreathers or deep tech, which may).
If it doesn't fit well or isn't intuitive to use, the Ferrari gear might even be worse. It's sort of like the ocean is actually your car, and your gear just a means to keep you seeing, moving, and breathing while you see all the great underwater stuff.
Or not. I'm having trouble thinking of the right metaphor. Though I clearly know what I'm trying to say ;-)
