Diaper pail recommendations

M
I know a lot of people say diaper pails are unnecessary, to just walk outside to the trash can. Well I live in an apartment and it's not logical to go walk down two flights and outside the complex to the trash can every time there is a dirty diaper..so I want to know which diaper pail is actually best at keeping the smell to minimum. I have heard mixed feelings about diaper genie but not sure what else is good or better.
