Since EMS Sasuke is basically Itachi without Tsukuyomi and with spamming potential, also Jiraiya encountered the MS techniques before(Minus Susanoo) which makes him one of the worst opponents for Sasuke. Jiraiya definitely has stronger ninjutsu, whereas Sasuke has more sophisticated ninjutsu, plus Jiraiya has more stamina and chakra. Therefore, since Jiraiya can take on Itachi(from Prime Itachi vs Prime Jiraiya thread) and potentially has a better chance of winning than Itachi, and Sasuke has similar abilities to Itachi, Jiraiya wins.
