Audit or tax? which to chose for articles?

hello everyone. i have cleared my IPCC Exams. i am looking out for articleship.

should i opt for Taxation Or Audit?

please let me know on what basis i should make the judgement.

in ipcc i was never very fond of tax, honestly. however, everybody says that audit can become very monotonous and tax is challenging and dynamic. 

is this true?

what Scope is available for both?

please let me know. thankyou.
