DOT 3, DOT 4 and DOT 5.1 (poly-ether glycols plus borate esters for DOT 4 and 5.1) are completely compatible.
DOT 5 (silicone) is NOT compatible with anything else!!! It is good for trailer queen show cars because it does not absorb water or damage paint, but it is compressible (squishy brake pedal) and I would not use it for a "driver."
DOT 4 is the current "mainstream" brake (and clutch) fluid and is more than adequate unless you are going hard core racing.

I agree with Barry and Jim. Castrol LMA (DOT 4) is still available... use it. And as with any hydraulic fluid, change it out every 3-4 years.
