According to cameradecision.com the G15 scores 85% on street photography to 80% for the G9X. It has the viewfinder which some find very useful and nice to have and 5x zoom vs 3x zoom with a bit faster lens. But it has a smaller sensor, slower continuous shooting speed and weighs more among other things. As good a deal as this one is you can probably try it for free if you decide to resell it, or at least for very little cost.
Mine is the G9, no X. Looks a lot like the G15 above, has the viewfinder and a bit longer zoom (6x), very similar specs. I think I’ll keep the G9.
