I am currently on RM77 1MB package. So far the speed has been reliable (with the exception that for the past 2 weeks my Streamyx was down due to bad wiring).

Usually I will be getting around 1.5MB down and 400kb up in Speedtest.net :

Not worth the extra $$$ to go for 2MB where in actual fact we are not sure Tmnet network can cater for sudden increase of bandwidth consumption with this upgrade promo. I would just wait and see.
