Mathematically speaking no. Asura has more advantages in terms of general stats.>Speed
High balling Broly he would be FTL at most. Asura is MFTL at his best>Raw Strength
Asura held up against a planet sized guy actively pushing on him while at his weakest state. Broly would be nowhere close to that. Blue Vegeta couldn't lift 1000 tons>Smarts
Broly is more Asura before he got thousands to millions of years of training>Experience and Skill
See above. Fairly certain Asura spent most of that time fighting things far more dangerous than what Broly fought during his time on his planet.>Misc abilities
Asura can regenerate with mantra while Broly can't. There is also the nature of mantra vs ki. Asura canonically has infinite wrath mantra at peak and the nature of his strikes could very well bypass or overwhelm Broly's defense regardless of how strong he is and make him explode. If they want to stretch it with the revival times (going from millions or billions of years down to two days by the end) it might be too difficult to put him down
There is also the event horizon vs gravity training stuff and how Broly's actual portrayed power being somewhat flimsy to accompany the scaling. Best displayable feat he had was when a beam collision cracked their way into another dimension which is something Asura also did. If they really wanted to (and likely piss people off) they could put him to comparable levels if they truly wanted to (Blue Gogeta + Broly beam = large dimensional crack! Nirvana Asura punch = large dimensional crack!)
When you get to going only by scaling you could wank anyone to any level if you try hard enough. It could go either way but even if you take scale wank at face value this might just be one of those cases where the other guy has the tools and skill to potentially win regardless.
