Series 5 vs SE gen 2. Which the better watch?

[Cyberdoc71]

Hi,

Recently was given an Apple Watch SE gen 2 but I also have a Series 5 I purchased few years back. Both are 44mm aluminum with exception SE gen 2 has cellular while the Series 5 is purely wifi. After doing research the only difference I could detect is the SE has a faster processor and crash detection. So wonder which is the better watch?

Thanks

S5 has ECG and AOD. SE2 does not.

What is the battery health of each?
