I'm in the same situation as you (check this thread https://www.reddit.com/r/AppleWatch/comments/17v46zh/apple_watch_6_screen_cracked_now_what/) . Mine cracked and still works though, so I decided to order the Ultra 2 to use as a more sturdy and everyday watch and have the AW6 SS for when I need a more elegant look.
The Ultra 2 arrives tomorrow, so I can't give any feedback yet on if I prefer it.
