Partnership or sole trader? Help!

Hi,

Me and my husband want to register small business and we are looking for better legal entity for us.

ME: I am student and work part time ( My working rights are limited, part time during school terms and full time during holidays).
HUSBAND: He is with full time working rights - at the moment unemployed.

We are looking which legal entity is better option for us partnership or sole trader?

I will be able to register my contribution work in the business just during the holidays.
