Think about it from the point of view of a fixed wing pilot in the last 500ft on approach, are you looking for crossing traffic to suddenly jump out at you, or just on your runway alignment and possible conflicts on the runway.
As for ADSB IN, it depends on what you have hooked up to it for it to be useful, that could be an ACAS device or just flight bag traffic features, if its just flight bag traffic, are you going to look at that at 500ft on final?
I find traffic displays are pretty good when approaching a destination, until close to the circuit. After that things happen too quickly for you to be monitoring the displays, esp in heavy traffic. The radio and a good lookout are more important.
Also close to a circuit you will probably get a lot of alerts from irrelevent traffic, confusing the situation.
