Hii Ganesh,

It all depends on what field you choose.Both the colleges have it's own pros and cons.

The IT department placements is good in Acharya Institute of Technology, this college is good for branches like CSE,ISE and ECE.

And  New Horizon is located near to the most IT companies ,also it is one of the best colleges in Banglore ,the placements scenario is amazing too.

So now it's upto you to decide.
