The baritone is known as the easier instrument.
A mellophone is a marching french horn while a marching baritone is well, a baritone. They have much different ranges, baritones are considered low brass while mellophones are in between trumpets and low brass.
It actually depends on what your playing them in i.e. a Brass band or an orchestra. Most marching/brass bands use the tenor horn, baritone and euphonium as the mid octave voice. Orchestras use the french horn because of its smooth versatile tone and range. The valve configuration between the French horn and the baritone is different. The baritone, Tuba, cornet, trumpet etc all use the same valve/finger configuration. So really the decision is down to where you see yourself playing in the future. Remember most good brass players are able to switch between similar instruments (i.e. those with a similar size mouth piece ) easily
that totally depends on the player person.... but usually the baritone
French horn, trumpet, tuba, bar-sax (also part woodwind), baritone, euphonium (like baritone, but with straight top).
