question How would you rank the following variations of a domain name?

[nomen]

Interested in how you guys would rank the following variations (or the modifying keywords) of a domain name (say you've got an e-cart app in the works):

cart.com, cart.net, cart.io, cart.co, icart.com, ecart.com, mycart.com, thecart.com, smartcart.com, easycart.com, supercart.com, cartly.com, cartsy.com, quickcart.com, fastcart.com, procart.com

Me:

1. Cart.com
2. MyCart.com
3. iCart.com
4. Cart.net
5. TheCart.com
6. eCart.com
7. EasyCart.com
8. SmartCart.com
9. Cart.co
10. Cart.io
11. Cartly.com
12. ProCart.com
13. SuperCart.com
14. FastCart.com
15. QuickCart.com
16. Cartsy.com

What I'm interested in is that how you evaluate common modifiers of a brand domain name (be it a tld, extra word, or affix) based on frequency, effectiveness or just your personal preference.

Thanks in advance

P.s. Did I miss some really obvious variant? Go ahead and add it to your list.

1.cart.com
2.icart.com
3.ecar.com
4.smarcart.com
The rest- hard to say.

1. Cart.com
2. iCart.com
3. eCart.com
4. myCart.com
5. SmartCart.com

The rest are distant but the above 5 are kick-ass domains for an 'e-cart app'

1. cart.com
2. icart.com
3. ecart.com
4. mycart.com
The rest are distant.

We agree with the first three.
