Same torque, different philosophy. Both put out 12 Nm, but the R12 V2 gets there as the value play - it undercuts everything around it and still feels like a proper direct drive - while the Alpha EVO 12 spends its extra $120 chasing signal quality. That shows up on the rubric as the one axis that separates them: fidelity. Simagic's 5-pole servo with zero-cogging tuning is the smoothest thing in the mid tier by most accounts, and if you have spent time on a cheaper base and found the FFB slightly grainy at low speed, that is the itch the EVO is scratching.
The thing is, the R12 V2 is not the base you settle for. On the R12 you feel every bump and undulation, kerbs are crisp to the point where you pick out the individual ribs, and it lands all of that for the price most brands charge for a wheel and base together. It is the base that made the rest of the market recalculate. So the question is not whether the MOZA is good enough - it plainly is - but whether Simagic's smoother signal and active cooling are worth a 30% price bump to you specifically.
For most people I would take the R12 V2 and put the $120 towards a better wheel or a load-cell pedal set, because that money moves your lap times more than the last few percent of signal polish. The Alpha EVO 12 is the pick if you are the sort of driver who notices texture, runs long stints where cooling matters, or you are already buying into the Simagic ecosystem and want to stay in it. Neither is a wrong answer - they just weight value and refinement differently.
