Its all a matter of preference, none is strictly 'better' than
the other.
I prefer classical acoustic (nylon strings) for my own reasons.. i
find it:
1) Feels more natural.. i like how it seems like the sound is at my
finger tips, its more 'raw' in that sense.
2) Nylon strings produce a thicker, more mellow sound, which is wat
i like.
3) Its much less hassle to set up.. in fact, no set up is
required.. just grab and play. I hate spending time hooking stuff
up, but no choice when im studio jamming. Very often my firends n I
simply jam with acoustic guitars, including acoustic bass.. but our
drummer feels left out
