Clone separate branches separately or one repository is better ?

Hi :),

I am using mercurial for software development and having 8 branches in a single repository.

 Regularly I update to other branches to do some changes for that branch.

My question is, which is the better way of software development in mercurial with branches ?
1. Can I clone each branch separately and change directory to the branch  whenever it is required ?
Or
2. Clone all the branches and doing it in single repository ?

Which is better ? And why ?
