If you can pony up for the 24-70, go for it. 2.8 produces some beautiful bokeh. Just beware it is one heavy son of a b*tch (nicknamed the brick). However that being said if this is your only lens and you want a touch more tele the 24-105 is also VERY nice. you lose 1 full stop of speed on the aperture end but that might not be the end of the world for you... especially for the price difference. I love my 24-70mm 2.8 and it's my go to, most used lens but I think I'd be 98% just as happy with the 24-105mm, I'm just a whore for extreme bokeh from the f/2.8.
