I have been using Neutrogena sunblock for some years now.
As one of the whitest white girls I know .. I burn very quickly and very badly (15 minutes of unprotected exposure starts to pink my skin and leaves me uncomfortable). My Momma (also a fair skinned maiden of rapid burning skin) introduced me to the Neutrogena line of products when we were getting ready to hike Whitney the first time a few years ago. It is now the only sunscreen that I'll use.
I enjoy to "hike nekked" as my Mom calls it (I hate having shirt sleeves on and very much dislike the feel of a collar against my neck, so tend to hike in low necked or v-cut tank tops). I reapply sunscreen every 2-3 hours while outdoors and, so long as I remain faithful to this regime, have yet to experience a sunburn. Be it in Death Valley, at elevation on Whitney, or at the beach...
