New "For fun" Horn...

I am by no stretch of the mind a professional, or even a semi-professional trumpet player, but brass instruments are and kind of have been my primary hobby for the past several years. I have my dream Bb, a decent flugel, multiple cornets, and more vintage horns than one can shake a stick at,most of which I inherited. Would a casual like myself find more fun in an Eb, C, or piccolo trumpet? Which would be the easiest for someone like me to pick up? Thanks
