I think barrel length is a matter of personal preference. Having said that, I prefer 28" for grouse and woodcock. I'm not sure why except that I'm 6' 1" tall. In tournament guns, the 26" are real dogs in terms of the market. Game guns are a little more forgiving, but still not as popular as longer barreled guns. I think 26" are clearly harder to sell at this point in time. That may be a fad and may change down the road, but for now.... In terms of grouse and woodcock, hunting in a woods, many shots taken quickly and with a sort of spray and pray type of shot, I really doubt if 28" are an advantage over 26". 30" in an aspen thicket might even be a hindrance. Just my humble opinion though which is what you asked for. ;-)
