I have an...
An everything, at least one, sometimes two, three or even four of Everything.
I spend most of my time in an Orca or a Beluga.
But I use my other ships - they're tools. The right one for the right job, and life is great.
Sometimes though, I use the wrong tool, to challenge myself. Turn a screw with an axe? Sure, you can do it. Cut down a tree with screwdriver? Sure, you'll be at it for a long time.
Usually I learn things doing this sort of stuff - it's how I came to appreciate the Orca and the Beluga so much.
