Both are pretty featless in regard to comparative stuff, though considering Yajirobe has enough potential that he was arguably stronger than 22nd TB Tenshithands from a lifestyle that didn't seem to require him facing anything that BoDB Galu didn't on a daily basis, evidenced by him referring to even oneshot material like Cymbal as incredible, and had two climbs up Karin Tower to boot, I could see Yajirobe maintaining the lead. If their V-Jump levels of Chaozu at 610 and Yajirobe at 970 for the Saiyan battle are anything to go by when Chaozu put a lot more effort into his training, I'd say it's not improbable for lazy assed Yaji to win.
