I just switched from glass to plastic and life has gotten a whole lot simpler. Easier to clean and easier to transfer to secondary glass carboy. Just drill a hole (before you brew obviously) an 1.5" or so from bottom of bucket and add a ball valve, gravity does the work and little oxygen touches the beer.
Not blowing off the primary has had little effect on the taste of the beer, just a little more head ache the next morning.
