The E should theoretically win, if technological patterns are consistent.
This is the key. We have no idea if technological patterns are consistent, or if Abramsverse tech got a jump-start due to timeline contamination. We have no data one way or the other, so both scenarios -- that Abramsverse weapons of the 23rd Century are comparable to those of the Prime 23rd Century, or that Abramsverse weapons of the 23rd Century are equal to or more advanced than those of the Prime 24
th Century -- are plausible.
