As a fellow horse owner, bezels mean less cleaning, less grimy bits I have to clean and less places for horse hair to catch. That said... both are lovely!
I ended up ordering the asscher because it will be a band to wear when I am not comfortable risking my engagement ring. Mainly horse shows etc. It is also different than what I have already so it gives some variety. I also love the light yellow. I constantly go back to it so I think it was the right choice.
