Is bcg better than chemotherapy for bladder cancer?

Possibly: Bcg and chemotherapy are 2 entirely different forms of therapy for bladder cancer and for different types of bladder cancer. In the initial phase of treatment, BCG may be a very good initial treatment but depends on the type of cancer and stage. If the cancer recurs or is invading the muscle of the bladder, then BCG is generally not an option and the next form of therapy is surgery or chemotherapy.

For early stages: For superficial cancer which does not invade the muscular layer of the bladder, BCG administered in the bladder is superior to chemotherapy drugs administered in a similar fashion. Bcg reduces the risk of recurrence, but may only delay progression in the long term. Bcg is not appropriate for muscle invasive disease, but some chemotherapy drugs given IV are very effective against such cancers.

Yes: Yes b c g is better tolerated by patients than intravenous chemotherapy. But if you thinking of intravesical chemotherapy than there is no difference in the tolarability or the effectiveness.
