  If you say that something sets your teeth on edge, you mean that you find it extremely unpleasant or irritating.

GG5 浮く - Sense 3: 〔歯が〕 be on edge; feel loose.

Not sure either is a metaphor. The kokugos don't seem to have these in the same sense of 浮く.
I suspect the use of 気障 (きざ) is just indicating what puts one's teeth on edge.

https://www.jlogos.com/d004/5351237.html

I must point out that this entry is very confusing to a non-native speaker of English, because it is not clear which of these tooth-related glosses is a metaphor and which is literal. Would there be a non-tooth-related gloss available somewhere?

Also worth pointing out that there is the word きざ appearing in most Japanese definitions which is not apparent in this entry.

that's the only sense in gg5, so making the switch

I think that the "equal terms" is coming from the adverbs such as 互角に and 堂々と. If it was implicit in 渡り合う, why would they be added? Both the JEs and kokugos have them.

sankoku and koujien explicitly say that it's fighting on equal terms, most kokugos use "相手になる" which basically means the same thing in this context and generally all dictionaries go out of their way to use "互角に" in examples

Sense 2 doesn't indicate respect, but I'm not sure if it's to the point of deserving [derog] or not.
I was going to give sense 2 [arch], but the 斎藤和英大辞典 and ALC examples are clearly more modern.
