Hello Riya, Both services are better in their respective field, it totally depends on in which field you are interested in.

In Judicial service (law exam) selected candidate only will directly become a judge of the court or member of judges or committee member but In civil services selected candidates are eligible for various position such as IAS, IPS, IES, IFS, IRS, also judge of the district court and many more.
