**Notes**
Castrol LMA is very good at rejecting moisture and may be kept in your brake system for a couple years. The LMA stands for "Low Moisture Activity". It comes in plastic containers which do not have a long shelf life. Don't buy lots of this stuff at a time because moisture can make its way through the plastic containers.
Ford Heavy Duty DOT 3 is VERY inexpensive and is popular among racers because of its excellent dry boiling point. It absorbs moisture quickly, but the racers don't care since they change their fluid frequently. Comes in metal cans so it may be stored. My understanding is that this fluid is deprecated, and the new part number is somewhat of an unknown quantity. You still might be able to find the original on the shelf at your Ford dealer, though.
ATE Super Blue Racing and ATE TYP 200 are the same brake fluid in two different colors (blue and amber, respectively). BMW recommends this brake fluid for their street cars because it, like Castrol LMA, absorbs moisture very slowly. The advantage over LMA is that ATE has a much better wet boiling point. You can put this stuff in your car and forget about it for a long time. An excellent choice for a weekend track car which also sees regular street duty. Comes in metal cans. The Type 200 appears to be out of production.
Valvoline Synpower is new to me. It was recommended by a number of persons on my regional list. Given that it's <$7.00 / pt, I might give it a chance in the near future. Comes in plastic bottles, so only buy what you need.
Motul Racing 600 is a very exotic and expensive synthetic fluid with high wet and dry boiling points. Too expensive for the street and requires frequent changing due to its hygroscopic nature. Sold in plastic bottles. It is not suitable for the street because it absorbs moisture quickly.
Castrol SRF is a hyper-exotic and hyper-expensive brake fluid that is generally used by wealthy Porsche owners at track events. I've seen prices of $78 per liter for this stuff. Sold in metal cans. I can't afford this stuff!
Performance Friction High Performance DOT 3 has a good dry boiling point but a crummy wet boiling point. It comes in metal cans which is good for shelf life and sells for $7.87 per 16 ounce container. If you are even considering this fluid, I would go with the cheaper Ford Heavy Duty DOT 3. In either case, change this fluid frequently due to the poor wet boiling point.
Neo Super DOT 610 is a DOT 3/4 compatible fluid and contains no silicones. Has a low vapor point to aid in the prevention of vapor lock. Comes in metal cans and can be stored. $13 per 12oz can. *Thanks CJ for pointing out this fluid.*
