There's no better place to get views of the Bay! Angel Island is a unique backpacking experience, one I'd gladly do again. It's worth knowing that Sunrise is completely exposed, and the Bay is notoriously cold, windy, and foggy; you'll want to bring enough stakes to guy out your tent as there isn't any wind protection from trees or boulders (which also means an unobstructed view, so there's some give/take here).We were prepared for the exposed conditions, but were surprised to find that the water spigot at Sunrise was not working when we arrived, and this was not mentioned anywhere during the reservation process, or mentioned by the ranger when we checked in. They did have a large container of water for each campsite, and since we only stayed one night it wasn't a huge deal, but we had no idea we were going to need to ration our water, which is an unpleasant surprise.
I've seen some complaints about the foghorn all night- it wasn't too loud from Sunrise, but I'd bring earplugs just in case.
