Four, there is the ADuC series from Analog Devices as well.

Agree'd. One note about the STR chips. Unlike the others they do not
support serial ISP. They were apparently planning to originally but
support for it appears to have been dropped. Generally with these parts
it's not so much one part being superior to another but each one having
it's own strengths and weakness. One area that appears to be quite
different across manufacturers is the interupt support. Each company seems
to have taken a different approach. At least they are different enough
there is little chance of confusing two of them.
