For me one of the easiest calls would be to say that we are still on top as we are yet to peak and shouldn't have fallen off by s63, but we might be past our absolute peak. Toronto seems like another obivious choise as they are getting close and their peak might fit the timeline better, but Im bit surprised if we don't get some kind of rivalry going on with them as our peaks hit so close to each other. Tampa Bay also looks like they are on good trajectory to be competitor around s63 but they still have so much to go that anything certain is hard to say at this point. And based on what I have seen so far I doubt I can ever really count Calgary, Edmonton or Buffalo out, with special mention going to Hamilton who managed to pull a rebuild/retool during one offseason so why they cpuld do so again in future.
