Ross' playing is extremely accurate and all, but for my taste it lacks the Italian or rather Southern Mediterranean temperament this music encapsulates, even in the pieces he wrote before he left for Iberian regions. Southern Italy belonged to Spain at the time, and much Italian music has Spanish characteristics and vice versa. Domenico Scarlatti was open to these influences. There are plenty compilation recordings that are much better at displaying these characteristics than Ross' complete set, even though it is now available at bargain price.
There is much baroque music that is not sounding as homogeneous as we today, trained more in listening to later 18th century "classical" music, expect it to be. These pieces were not supposed to be "works" in the sense of "opus" that late 19th century musicology defined it. They are "suites", a series of pieces sharing a common key, and supposed to entertain, display varying and ever changing moods to excite the senses.
There are many different ways of balancing a compositional "whole" and entertainment, counterpoint and superficial accessibility between Bach, Graupner, Telemann, and their contemporaries. Just let yourself get carried away through the changing moods and your will get the most from this music. I, for one, find it more exciting than the more homogeneous later sonata and concerto forms, just like I dig 17th century operas more tha 18th century with their excess of da capo arias.
