Who's reviews? Let's compare the 70-300 with an L lens covering the same range: at 70mm, the difference in the center isn't huge, although away from the center is another story; at 300mm, the center is worse, and the mid frame (corners on APS-C) is much worse. Hidden L lens? Maybe hidden behind a layer of vaseline smeared over the front element of an actual L lens...

Ok, I exaggerate a bit - if you stop the 70-300 down to f/11 at 300mm, it's great...no, wait...it's not, even then the corners are mushy mess and the mid-frame isn't much better. Ok, I keep exaggerating. Actually, if you stop down to f/8 and keep it under 200mm, it's ok. But hidden L lens? I think not...
