I used Langman's and liked it (and I hate textbooks for the most part), but I can't compare it to anything else. I used it in the first place because my professor teaches the basics and then pulls a good chunk of his questions from the assigned reading from that book. I did well in the class and feel I have a firm grasp of the subject after using that along with lecture/youtube
But honestly for me videos/drawing stuff out is really what did it for me. Also embryo may be nearly worthless for clinical but isn't it really important for boards? I could be wrong about that but that's what I've heard.
if you really want/like to use textbooks maybe flip through both and see which one looks friendlier to you, but definitetly check out some videos because Embryo is very visual.
