Like you, I adore (JW) action music. His style is so detailed, rich and seamless, jumping from one theme to another, and the evolution and clever use of theme. For instance, the Slave Children theme that goes from dark at the beginning of the movie at the village, to heroic at the end at the bridge. Impressive and beautiful. JW is so good at this, that I sometimes recognize differently adjusted themes years after listening to the OST or watching the movie.
TOD is one of those OST that solidified my love and appreciation for JW music. He didn't have to write a motif for the water escape, or the cart chase, or all the catchy action cues, and yet he did, and it makes the movie better for it. All of this music work make this movie unforgettable. I'd say the TOD OST has the strongest identity of the 3 Indiana Jones movies, maybe because it's the most action-packed, in your face but that's exactly why I love it. It's a ride of an OST.
I'm not necessarily saying it's my favorite, as I adore Last Crusade too, which has a very different musical identity. As weird as it sounds, Last Crusade gives me European vibes, because of the composition, and the religious/holy motifs mostly at the end of the movie. It definitely has more heart and is very different.
I wish we had genius music like this for today's movies, JW or not (when applicable of course, ie. action movies).
