LTS it is more stable and has long support so u don't need to upgrade every time
The HWE support better the newer hardware and you will receiv the new features
Anyway u can install both in your deepin system( make a backup of your system first) and switch it at boot GRUB menù
LTS is better if you are focused in the the stability ( avoid troubles at maximum)but if you are an average user and you don't want wait long time for new features you can stay with the HWE ( it is enough stable).
Can someone explain to me what the difference is between stable kernel and hwe kernel?
