This thread reminds me of a topic that might be worthy of it's own thread. The debate between using a 7-string versus a 6-string baritone and a "normal" 6-string.
I chose the baritone because I could play it like a normal guitar, but use heavier strings. I felt that going with seven strings might end up with a string gauge compromise, plus the whole getting used to having an extra string! Since the scale is longer to help with the bass, that also messed with the highest string. For me, I was definitely willing to lose the (minor in my opinion) bit of extra functionality to do a high lead while having the extra low string.
My fun little noob song Berry Jam was made with the baritone (hence the name) along with a Les Paul for the leads. Please excuse the drums, I play all the instruments, but had only been playing drums for two weeks when I made this! I had started to make replacement parts when the shit hit the fan back in 2009 and it never got updated...
