There is nothing wrong with BTECS, they are designed specifically for employment however you can still go uni with them if you have a specific career in mind.
I do a BTEC, i choose that instead of A levels because of the route i want to go into.
If you know what you want out of life do a BTEC but if you are not sure, do A levels to keep your options wide open.
The ultimate decision is yours, speak to your parents, they should know.
