Besides obvious choices like the Heavy Plate? I like the general aesthetic of the native Heraldic Mails, as many do, but there are a number of things about them that are a deal breaker for me. The mail texture on all of them is ridiculously blocky and low resolution for some reason, which makes the sleeves on all of them and the hems of the surcoat variant look ridiculous, and the tunic variant has those derpy looking kneecops that totally ruin the look. The fact that the ends of the sleeves also clip through most of the non-native glove models is also a point of irritation for me. It's like Taleworlds wasn't even trying with it.
