this question appears every year asking if buying the n pixel or wait for the n+1. ina few months there will be the 9a a few months after a 10 a few months after the 10a in a years' time the 11 and so on and on
just get one recent which is going to be supported for a long time that match your style. some are waiting because they don't like the camera strip on the current phones.
you'll be fine with either until it ends getting support and stopping gos updates and then change. new phones have 7 years support, you'll be set until 2030 at least unless you need to scratch the itch of having a new phone.
