Apart from improved image quality with a full frame sensor (or larger format films), the other difference is the bigger the sensor, the shallower the depth of field is at a given f-stop. So this is important for portraiture and when using fast primes for out of focus areas and getting a look. If you shoot Macro however, then maybe this is not a good thing for you.
At a pro level, having that look is all part of standing out from the crowd and making a signature shot.
But don't despair, we have film, you can do it, it ain't nothing new. Old school is good school!
