Either will work well depending on how they are set up, maintained and the conditions of the day. Brakes often see little maintenance...rim brake pads can dry out and are often glazed...disk brake pads are never cleaned and get a build up of dust, dirt, etc. that can affect effectiveness.
I'd prefer disk because they work as well in the wet as dry compared to rim brakes which lose 'bite' when the rim and pad become wet.
I raced through the '80's and '90's on rim brakes and had no problems except when racing in the rain...brakes lose grip so you have to pay a lot more attention to what is going on around you.
That's all I got...take care of your brakes and they will take care of you...
