My limited knowledge has taught me that there are minor differences between manufacturers. The most significant one that I am aware of is with the rated boiling points, which, in the case of the wet boiling point in particular, is a reflection of the fluids ability to deal with absorbed moisture.
Any brake fluid meeting the DOT 4 specification will be suitable in any vehicle that requires DOT 4 brake fluid, assuming that it is being driven under the conditions that the vehicle manufacturer intended. i.e. public road use as opposed to being used as a race track motorcycle.
This also assumes that the fluid will be flushed at the intervals intended by the manufacturer.
In my opinion, more so than a particular brand, it is important to buy brake fluid from an established and reputable brand as opposed to a no-name/unknown brand fluid such as is often found in convenience stores- I have no desire to use brake fluid labeled as Top Dog Dot 4 Brake Fluid that comes from parts unknown. Hopefully this increases the odds that the fluid that is in the container is actually what the container states that it is, and that it actually does meet all DOT 4 standards needed to be labeled as such. Which one of those particular brands is of less importance to me.
