When I was looking for zoom lenses to get down to 24mm I wound up with the 24-105 f4 as it has IS. Only time it is needed is for low light situations. Works fine for my use, stationary subjects, but for freezing motion the extra stop could have changed my decision to the 24-70. The choice with any lens decision needs to be based on what you want to use the lens for. Of course a tripod could be used with the 24-70 but I still prefer to travel light, so don't always carry a tripod with me, much of the time.
