This is a qualitative question. A matter of opinion. There is no one, "best" instrument. This question would be better asked as a poll.
As a musician, the tuba has some very fun points, particularly the opportunity to be the counter-melody. The tuba is the lowest pitched instrument in most orchestras, which can also be fun to play. However, the tuba (as the lowest instrument) is generally scored as the metronome for school groups (middle school and high school concert band), which can get fairly boring.
The tuba is the largest brass instrument with the largest mouthpiece. In marching the Sousaphone and the Contrabass bugle (known as contra) are marching versions of the tuba. The contra is the lowest-pitched, largest, and heaviest marching instrument.
The Tuba is actually a German instrument.
