Is labetalol as effective as atenolol for pots syndrome and angina? I'm on Prazosin, and Verapamil but those alone dont control.

Not the same meds. Labetalol and Atenolol are not the same medications. Labetaolol has alpha blockade too along with BB. I am assuming you have Postural Orthostatic Tachycardia Syndrome. Would stick to a pure BB, short acting. Would talk to your MD. a pure BB will also help with angina. This is a imp discussion to have with your MD.
