A stiffer mount just move the drive train shock from basically a constant stream of small clutch dumps to the next component in the system. Personally, I find after a year I am able to shift the car without the engine rocking around even during hard acceleration. The only time I find "wheel hop" is WOT in slippery conditions. But it's not during a shift it's when it hits a bump WOT and the road's not able to handle the torque.
During steady acceleration there aren't issues with the stock mount, it's already loaded. It's between shifts, you let off the gas the engine rocks forward as you engage another gear and then pulls back when you get back on the gas. This movement is undesirable and actually causes more wear to components and makes for sloppier feel of the shifts. I've driven both this 3 and my previous 3 with stock mounts and I was perfectly capable of being smooth, but with the RMM changed on this 3 it's even better and also makes it more forgiving of sloppy shifts (nobody shifts perfectly 100% of the time). Also when rolling in first gear in stop and go traffic it gets rid of some of that bobbing/shaking when getting on and off the gas.

Anyone who argues that an upgraded RMM is not worth it has either never driven a car with one or is an idiot.

And as for vibes...just get the stage 2 cpe or a ~60 duro. The only time the vibes are noticable is when idling with the AC on.
