Best - BSD, FT. I also liked I500.
Worst ...... ugh loads of them ...TOM, JM stand out as very annoying
Worst but improved .....Tommy !! Often cited as one of the worst. Do nothing and you score only a few million less than if you try to play it. HOWEVER ...this has been much improved with Chad's 5.0 code .... now at least different points are assigned to different targets, and the scoring has been buffed so you are encouraged to play
