Coming from a commerce background, BBA-LLB will be a better option for you. BBA-LLB will give you exposure to two different professional disciplines - management and law, plus the intersection of these two. It will give you a better grounding to pursue both LLM and MBA, should you wish to study further. On the other hand, BA-LLB will give you exposure to only law (and nothing else). The BA portion does not give you exposure to any specific professional discipline and subjects. It is just a collection of humanities subjects to complete the required credits.
In today's scenario, most have a BA-LLB degree, hence if you ask the question they'll obviously show preference towards the same. BBA-LLB is a relatively new degree. But before deciding, think about 20-30-40 years in future. The fact that today there are a lot more universities offering the BBA-LLB degree should tell you something about the emerging trend and the growth trajectory.
My advice. If your goal is to make money through a job without sacrificing the iota of life left in work-life balance axiom, don't do law in the first place. Whichever degree you choose, life would be hell after you graduate. And if you are not overzealous about litigation or corporate law, you would regret your decision of taking law the most in your life.
