Brake fluid DOT 3 or DOT 5

Looking for advice from someone who has ran both fluids.

Is the stopping power better on the DOT 5 and is it worth clearing all the braking system of fluid to switch over to the DOT 5 for the much higher boiling point??

I would not go with the DOT 5 as it is synthetic fluid and will NOT adsorb any moisture...I used a Dot 4 fluid and have had no problems and when it turns a darker color just flush it out with new fluid....Good luck
