Which is better among BE and B.Tech?

There is no difference in both except the names and to confirm that you may compare the course structure of any branch for universities offereing B.E and B.Tech. For more, you may see my previous answers.

Some universities / institutes call it BE and some B.Tech, there is no difference except for the name.

both are same...merely name difference

Both are the same thing..some universities give BE and some B.Tech
