As Jonny says, depends on your riding. If you’re bimbling around the woods, riding marathons, fancy a bit of casual xc racing or generally prefer to keep your wheels on the ground then go spark. Upgrade to the 930 with the nude and carbon front would be nice.
If you have the odd BPW, peaks trip etc, look for the harder lines and want a bike even more capeable in the tech then the genius is the one. I’d look for this upgrade to 930 spec to get carbon and more importantly on the 150mm genius platform is the Nude rear shock giving you an even more versatile bike with the 120mm travel option.
