Logically their BoGs counterparts would be stronger since it's set 5 years after Daima but using the separate continuity argument Vegeta and Goku wouldn't have SSJ3 and SSJ4 respectively in BoG (which they obviously didn't at the time the arc was made). So Vegeta would have had to got well over 4x stronger since the Boo arc for his SSJ2 to compete with Daima SSJ3 Vegeta.
Not sure on the multiplier of SSJ4. I had it only being 2x SSJ3 in my pl list but that was because it was hampered by Goku's fatigue. At full power it might be a 5-10x multiplier.
