They're going to have quite a tall ladder to climb to become the "top model". Currently on LMArena they're nowhere near the top [0] in any of the important categories.
For me the issue isn't with the killing/eating of animals. Rather, it's how they are treated during their lifetime by the meat industry - which is essentially optimizing for the minimum conditions that can still provide meat that can be sold legally. I'm not a vegan by the way, but I can appreciate the moral case vegans make.
