Better to use 25w or 15w charger for overnight charging?

Since wireless charging was there I never bothered with actual wired charging. I just drop on the wireless charger overnight or during the day. I have many wireless chargers all around the house and at least for my use case never needed the super fast charging. Overall I think it shouldn't matter if you use 25 or 15W (phone should draw in correct power) unless you are super concerned about battery health for multiple years of use. I personally change phones often and even if you keep them for 2 years you don't have to worry IMO.
