If you plan to do any road riding, you'll want a helmet with a shield. If you can't spend over $100 now, you won't be excited to have to spend another $100 later to get another helmet with a shield.
I also prefer the flip up style because during stops you can get more air, drink and even eat some snacks easier. Also, chatting during off-road route finding is much easier.
I guess the main reason is that I have glasses and taking the helmet off and putting it on means removing my glasses both times. Easier to just flip the helmet up during the shorter breaks.
