Calling all sunscreen gods!?

Hi there, trying to make a decision on a good sunscreen to take to an outdoor music festival in the roaring sun. I'm aware of physical vs chemical sunscreens and honestly, I'm from Canada and haven't heard of more than half of the brands that exist. We do however have Mexoryl but not everyone likes it, it tends to be expensive and I cannot buy it in the USA anyways. I was thinking about sticking to something with Helioplex aka Neutrogena due to its photostability and read a consumer report about NO-AD, Equate Baby SPF 50 and another being among top best sunscreens for super cheap. I looked at the ingredients for NO-AD and they're very on par with Helioplex (exact same active ingredients in similar percentages) so that would make sense for NO-AD's success I suppose. Any first hand experience or advice on what I should use? Preferably non-greasy, not white cast.
