I come from a C++ background where it is always advised to use ++i instead of i++. It's just a habit. Does it stress you to read ++i over i++?

Of course not, I do use both. Admittedly i++ is a lot more common in Java, and for loops i++ is the standard idiom. Not using the standard idiom usually implies less practice, e.g. str.indexOf('x') < 0 is the standard one, not == -1. Even the backwards iteration is a postfix subtraction::

  for (int i = array.length; i-- > 0;) doStuff(array[i]);
