Only other phone that I know of in same class is the Huawei Mate 10 series. Camera has 1/1.6 aperture. Should be especially good in low light. Huawei has pretty good camera software too. I have Mate 9 and for android phone it has been pretty good experience. First phone I havn't rooted in years. More so because I havn't had time to play around with phone. Three previous phones were from Note series. Apparently the new iphones have terrific performace. I did sign up for Purism phone. But delivery date is Jan 2018. We shall see!
