OK, I've had my baritone tele for a couple of months now, let me try - the baritone is like getting a 24 fret neck, but the extra two frets are lower than the standard ones instead of higher. If you capo2, you basically have a strat neck. So the longer scale drops you a full step at the same string tension - C standard (drop C#, is that what you'd call it?) on a regular neck will be in Bb standard (drop A#?) on a baritone neck with the same tension. I was using a set of daddario .013 - .062 and tuning to B standard, which gave me enough string tension but it still felt too much like a guitar, and A standard was just too loose. I wanted a feel closer to a bass, with nice rich wound strings so I went to Ernie Ball .014 - .068 which is just right - B standard is nice and very snappy (can't bend much though) and A standard is good enough. Playabilty - long reaches on the lower frets are harder, but it's not a huge difference and chording is not very different. If you play super fast scale-based stuff it may be harder than it is for me with my pokey old school music. One annoying thing: Because the strings are thicker, it feels like the nut is a bit narrower. I'd get a 1.75 nut if I had the choice again.
Short version: Get much heavier strings, it'll make more difference than the baritone scale length, but if you want to get all the way to A, then yeah get a baritone. Try the Ernie Ball baritone set on your regular guitar (get ready to ream out the nut) before you get a new neck.
Max, what are you going on about?
