I can see this both ways. To be a great session player, I would have a 5, or even a 6, but they are not required...
I have only used 5s and I am building my first 4. I wanted to make a four, I could drop, or play stuff I didn't write to go below D. If I were a session player, I would have a 6 string, strung correctly, with an active/passive switch and a pick in my pocket... Just incase.
To each his own. However I will say on my five, I use the B string A LOT!!!!! I slid on it all the time, and if I play (my middle C... the one on the A string) I can sometimes fill out the mix with a lower octave C in there...
