for loop vs while loop

Which loop to choose, for or while:
1. If we know that we must loop a max of x no of times, then for loop. for loop takes index of how many times to loop.
2. We can use index with while loop too, but it seems more unnatural. eg i++ needs to go inside statements, but in for loop, it goes in for structure.
3. Moreover if we need to break for loop based on some condition, we need to use break statement; a little unnatural again.
