It still all boils down to the player...
A great player would probably make a 20 year old arranger sound better than an average home player on a T5 or PA3X.
It's obviously a given that an expert at just about anything is going to outperform someone average skilled performing the same task with the same tools.
The more important comparison is having that same great player play a 20 year old arranger, and then play the T5 and/or PA3X.
I'm certain both the T5 and PA3X will sound a lot better as a result of 20 years of keyboard technological advancements.
Have an average home player do the same thing, I'd expect the T5/PA3X sound improvement will be noticed and appreciated as well.
