The Cobb power gains are a fraction of what you can get with the JB4 but that's only becuase they have not released stronger maps yet, pro tuning software, etc. In theory they eventually should put down similar power as both can max out the small factory turbo. The JB4 gives you autotuning, in dash gauges/features, better diagnostic invisibility, costs less, but takes a bit longer to install.

The first mod as an Xdrive car should be coils! Speed won't matter much when your car feels like rolling over at anything above 75 mph because of the jeep stance. I have an x drive, that was my first tune. Do it, do it before you get the car lol.
