I would have to agree with several of the posts here that the only way to decide is to play the particular instrument and decide whether you like the sound of it.

I will disagree though on the number of types of mandos.

As one post acknowledged there are resonators out there in various types. Tri-cone and single resonators, in both metal or wood bodies, as well as my particular favorite the mandolin-banjo, available in different configurations in relation to body and scale size.

Pick the one that sounds good to you for the type of music you want to play,and remember if you play different styles, you may need more than one to fit those styles.
