I really like #3 and #5. I have #5 in sea green and they are gorgeous shoes. As far as how they compare to the d'orsay pumps you posted, the d'orsays are very elegant. But it just depends on if you want a peeptoe or d'orsay.
If you are looking for a d'orsay, I like these better than the ones you posted. I checked and you got your pictures off Dillards. These are also from Dillards.
I like #1 and #5, but I like #5 the best. I like #5 better than the d'orsays but like Meow said, it really just depends on what kind of shoe you want. I'm personally biased against d'orsays because sometimes my foot is too wide for them.
i like #5. i think that you can find a better basic black heel. if it is between the two, i would pick #5 definitely.

I like #5 the best and I like it better than the d'orsay pump, but like tri_sarah_tops, I'm totally biased against d'orsays because my feet are sometimes too wide for them as well.
I like the last pair of peep toes best. In comparison to the shoe you asked about well, I think the peep toe is way more fun and the other shoe is kind of stuffy. I think either could be worn in an office, but the other shoe is better for more conservative offices.
