Dr. Robotnik's Mean Bean Machine can be a good time or a great time either, but, it can be repetitive easily. I played it on its "single-mode" where you advance to predetermined stages with different enemies, the difficulty spikes can be punishing but once you manage to understand your opponent's strategy you may counter it, this aspect was the thing I liked the most and gives you a good challenge.
For the negative sides, there are like 2 songs for this game and the same background and it really feels through your gameplay, it doesn't feel that you advance at all and can be disheartening because the enemies will give you a lot of trouble. I didn't Vs a human but it seems to me that if you have a rival with a similar level than yours, both of you will have a fun time. I think that DRMBM for what it is can be very enjoyable, but, its fun may weary faster than you expect.
