I've played 4's predominantly over the years. Sound and comfort are what I look for. I've had a few 5's (Warwick, Fender,Birdsong) but always gravitated back to my 4s. Never been in a situation that really really had to have a 5 string so I play what I like, which is a 4. My choice based on my selfish wants!
. But play what makes you happy, is what say.
