No and No.
If you're talking J, LOT doesn't stack up hard product to AC IMO. 2-2-2 isn't the same as 1-2-1. When we're talking Economy...I'd say both are pretty on par, the food/service/entertainment are marginally better on AC. But that's just me. If you're Polish, or Eastern European, LO might be a bit better to you. I'm fine flying both.
But when it's J, I want aisle access without stepping over someone. You know who doesn't have that? LH. If money is no object, we're all flying LH first or something of that nature. But in a battle of J AC vs. LO, I'm taking AC. In a battle of Y AC vs LO, I'm taking whatever has a better price/timing combo.
