Hello student I'm sorry to inform you but no both are not equal as both are different and it will affect you in your graduation for example if you Pursue 10+2 in vocational stream then you're not eligible to pursue any science relevant courses such as engineering, doctor, pilot, Bsc etc.

But if you pursue 10+2 in Science stream then you can pursue any courses science relevant as well as vocational relevant.

But you should choose one in which you're interested and in which you think you can do better don't choose any stream, analyse your interest and capacity and then choose accordingly.

Feel free to comment if you've any doubt

Good luck
