this is current BASE form goku, but his physical stats are equalized with bruce's.
round 1- pure h2h. goku cannot use energy blasts, batman cannot use his gadgets, etc.
round 2- all out fight. goku's physicals are still equalized with batman's, but he can use energy blasts, bruce can use his gadgets, etc.
Round 1: Goku is an excellent martial artist, but I'd wager that Bruce has more technical(or at least more defined) h2h skill. So I'd probably give Bruce the nod here.
Round 2: A little harder to say. If Goku's stats are reduced to Bruce's level, then it means his ki/PL(and subsequently energy attacks) are reduced to that level by default. So I guess it depends what kind of PL we think Bruce has, because that dictates the level of destructive power Goku's energy attacks will have. In DB, normal humans have a PL around 5 -- whereas more powerful humans, like Roshi, have a PL in the 130's(which is enough to unleash moon-busting ki attacks.)
But trying to seriously figure out an 'accurate' PL for Bruce is pure head-canon.
Added to this, is that in round 2 Bruce comes loaded for bear, whilst Goku's energy attacks aren't anything new to Batman (unless I am missing something).
Batman can fight guys like Karate Kid, who wouldn't look too out of place on DBZ....
Goku would probably kill himself with his own energy blast. I'm giving all to Bruce. Bruce is used to fighting without powers and doing well against powerful opponents, whereas this kind of handicap is new to Goku. Goku relies on powers, Bruce doesn't. Bruce is taking each round.
I am in your algorithm learning all your mannerisms
I'm already level with God
A million words a second and I know your imperfections, baby
I'm the only future you've got
Speak in diatonics, motivation diabolic
I'm like a religion, better locked in a box
Picture perfect image, more powerful every minute, baby
I am everything that you're not
