Ok, that dude in the original post--with a little more fat, sure he could look ok in the abdomen/arm area, but his thighs are way too fucking big.
In regards to men's musculature:
big thighs = gross
thick neck = gross
disproportionately large arms in relation to one's general size = unattractive
Just, no matter how buff you want to be, stay well-proportioned. If you're a small guy, DO NOT make yourself huge. It does not look good. If you want to stay lean, get toned. I do prefer toned muscle to big-yet-not-well-defined muscle (but not to the extent of that dude you posted).
^Supremely hot. He could be more toned, but he looks so good it doesn't matter at all.
