Should I join CTS or be in TCS?

I recently joined in TCS for Ninja role and mapped to ITIS domain in ILP training and at the same time once I joined within 10 days I got an opportunity to join in CTS for Programmer Analyst Trainee role.

What are your recommendations plz suggest me and I am struggling to take decision whether to stay in TCS or proceed with CTS?

But to resign in TCS higher officials are informed to me pay 50k for bond breaking.

Plz suggest me what to do.
