I don't think it's possible to predict how good any year is likely to be, regarding seeing aurora. There could be a stunning display, but where you are might be overcast, for example. Canada, Finland, Iceland, anywhere close to the Arctic, really. I've seen aurora in North Wiltshire, but every time there have supposed to be perfect conditions since they've either not shown, or the weather has been shitty. A bit like eclipse watching. Northern Scotland could be just as suitable, really, it all boils down to what the sun gets up to.
Best of luck, wherever you decide to go; pick a place that you're going to bring back lots of great memories of, with an aurora spotting as the cherry on the top, that way you won't be so disappointed if they fail to show during your visit.
