I don't play the Saxophone myself, but I typically prefer the alto despite my genre preference generally being more suited to the tenor. I just like the alto because I think it's size is better.
I've always imagined it to be closer in size and range to the trumpet. Maybe a bit deeper, and I prefer the alto's lower range, but I do prefer the alto because I like it's bright sound, which I prefer over the warm and mellow sound of the tenor.
Which of the two most common types of Saxophones do you like the best?
