Sharplow is genuinely so great because they have this sort of balance in their chaotic relationship. Like, one is more brawn and the other is the brain. And despite betraying Jude, Sharp still trust Judelow so much that he would pull out his kits in front of him because he knows Judelow wont steal from him. And Sharpness is definitely right because Jude actually is an honorable fighter and did, in fact, not steal from him despite acknowledging Sharp's vulnerability towards him.
They also have mutual respect on each other. Both have their own strength and weakness that each are trying to always one up each other. Judelow's great at trapping and has trap Sharp numerous time despite his ego denying it, and Sharp has killed Jude with his pvp skill with Judelow knowing Sharp is the better one between them. Yet, despite that all of that, Jude still manages to catch up to Sharp's pvp level and does great at surviving for a long time. Sharpness is not good at trapping (yet) but has already studied Judelow's pattern of either baiting, making a trap, or is generally just up to something.
I think that tells a lot about how they actually pay attention to each other closely. And even though they seem like enemies in their eyes, they still have the time for a normal conversation and laugh at each other's silliness. Even their friends see them as a thing because of the huge tension that is thirdwheeling the duo. Jude would mention Sharpness like an ex he never blocked, and Sharp will continue to hang out with them despite the whole betrayal thing. And when they banter with each other, they are in their own world, and theres just a universal rule to not interrupt them at all. Theres also just their close friends being done with their yearning for each other and also because they end up being the thirdwheel or get caught in between the duo's rage.
TLDR; Sharplow has the best dynamic, and they either know or don't know themselves as they continue to have this whatever weird relationship status you can call it.
