Closing thoughts

If given a choice, I will definitely prefer Apple Watch SE 2 over Apple Watch SE because of the much faster S8 chip on the watch. Crash detection is a feature worth the money. The nylon and sapphire crystal back should improve the strength of the back or rear side of the watch.

All other improvements are generic in nature. But, a faster processor is the best gain I can see coming of buying an Apple Watch SE 2 over SE.
