WHO IS BETTER FOR CLASS 11-12 ACCOUNTANCY?

I searched a bit and found that people have two opinions. Some say CA Hardik Manchanda is best while the other say CA Parag Gupta is. Who is actually better?

I want a free batch (if possible). I don't have a problem if the lectures are lengthy, the explanation should be crisp! Is there any other teacher even better than them?

Please help!! I'm very confused.
