I don't think it matters how many instruments, keyboards or whatever you own and use (or even don't use). At whatever level, you can certainly find enjoyment and fulfill your desires in similar ways. But I also think that those here who are professional, that gig/perform / compose, write or make a living from using these instruments deserve the most credit and have the most reason to find the correct balance and combo because you are pleasing not just yourself but also the crowd, you want your performance to sound as perfect as possible.
