Hi, I am about to buy my first AW and would like to know if the screen brightness is an issue at 498 nits for most situations. I have the 6s+ and it is rated at 450 nits. I don't think it's a big deal but just want to ask AW1 users if this is an issue? Also, is the S1p chip slower than S2. I heard they are same and GPU speed is identical. I don't need GPS. Is AW2 worth an extra $100 if I don't need GpS or waterproof?
