I like Pendlays over standard bent over rows because, like deads, you are setting the weight back down on the ground. For those of us with messed up, or weak lower backs, this is great because you don't waste a lot of energy holding up the weight in between reps. A lot of people don't like them because they can feel awkward at first, and may even seem harder... but after half a cycle of doing them I fell in love with them.
Also, is there a certain reason you don't like zigzag? That isn't a condescending question but I just feel like there is this bad aura around it that makes people not like it. Some of my best strength gains, and certainly my best hypertrophy gains in recent times came when I implemented it into my routine.
