is ies better or gate?

Clearing both the exams is equally good. If you are planning to go in for a government job, then both of them are good. However, IES definitely has an edge over GATE.

If you want to pursue higher studies such as M.Tech, then I would suggest that you go in for GATE.

There are a number of PSUs which recruit on the basis if GATE. Thus you can explore this option as well.

Both are different. Ies is conducted by upse and gate by iit. Ies is best and hard compare to gate.
