There are other questions that list the differences in the retail and educational version but I cannot judge which one I should buy (educational or retail).
I am buying Mindstorms for the first time, The educational kit looks more appealing to me as it has more parts, gyro sensor (I need this) and it is also $10 less than the retail version.
I am 27 year old and want to buy the best value for money and one I can get most out it. Any add-on suggestion will be also great as it is not available in my country and I would like to buy most of the stuff in one go.
