Which should I buy

So I'm currently thinking of buying an iqoo phone primarily the iqoo 15 ultra but I'm seeing other choices from the iqoo line up like the iqoo z 11 turbo or the iqoo neo 11, Im having a hard time choosing since I currently have 22k php ​and idk if I should save more up for the 15 ultra since the shoulder triggers,chip and the fan and camera is what I like most about it but idk if I should just buy the iqoo neo 11 now or what, I'm mostly looking for a strong chipset with good cooling and a good/decent camera (shoulder triggers would be nice tbh).
