These are the most popular ETA movements and oftentimes questions arise to the movements' general qualities and composition as a comparison. So, I hope this chart helps for beginners, enthusiasts and even WIS's as easy reference of sorts (though, I'm sure you have it memorized!). Please note that the standard grade ETA 2892-A2 & 7750 movements don't exist. Also note that there is no difference between top and chronometer grades, save for the lemons weeded out with respect to the stricter accuracy and testing in the chronometer grade. Further note that many of the other ETA movements are based on (added complications/modifications to) these movements. Here's a chart of some of the info on the ETA 2824-2, 2892-A2, & 7750 movements: ETA's holy trinity.
