<span style="font-size: small; font-family: Times New Roman;"]I've got both, and I would say that, overall, I would heavily prefer the 24-105 as a walk around lens. Focal length, and IS...

Even though I have the 70-200 f/2.8 IS, I'd still lean twoard the 24-105 if i could only have one. If I was talking indoor event photography, like weddings, I'd swing back to the 24-70 f/2.8... The speed is worth it. Otherwise, I much prefer the 24-105.
