My home town in Gujarat, & want to do B.Tech engineering course one from in between Sardar Vallabhai National Institute of Technology Surat & Dhirubhai Ambani Institute of Information and Communication Technology (DA- IICT), so please compare both institute & provide detailed information about that???

For B.Tech , DAIICT is better than SVNIT in my opinion.

Few things to remember:
DAIICT is only offers ICT and ICT with minor in Computational Science. (Similar to IIITs.)

SVNIT has been put up with "NIT" tag from 2002. From 1996, SNIT has all major engineering departments. SVNIT offers a diverse alumni base.

DAIICT was established in 2001. In just, 11 batches passed out , DAIICT has kickass alumni base

Faculty: DAIICT >> SVNIT

DAIICT : Total 42 professors (not considering visiting and adjunct faculty):
All professors have Ph.D. from well reputed colleges.
Best faculty you could find in INDIA.
+10 visiting professors & adjunct faculty.

SVNIT: Total 11 professors :
2 main professors (Ph.D.) ,
3 assosiate professor (1 Ph.D.,2 M.Tech.),
6 assistant professor (1 Ph.D.,5 M.Tech.)

DAIICT has faculty of SVNIT's combined computer+electronics+electrical departments and only Ph.D. professors while SVNIT has faculty with more than 50% M.Tech. professors.
