Thanks, guys.
Needless to say, my choice of lens was chosen to match my budget at the time of purchase. Now, I could go out and purchase the 24-70L, but to be perfectly honest, I've compared my work to others using the said lens in the same environment, and sure, I'd use the L lens if I had it, but I've seen no discernable disparity in image quality between the two lenses whatsoever. I also own the Tamron 28-75 L/2.8, which is a fair lens in it's own right, but it's noiser in both senses of the word, slower af and not as bright, even at the same aperature. But still, I've taken some of my best pics with it.
