Ciara's option is the cheapest and most speediest process. Also the EEA family permit she mentioned is not a visitor's visa. It allows you to travel to the UK, and once there you will need to apply for a resident, which gives you resident rights.
If however you decide to use the National rules avenue, you accompanying you will be considered as settled in the UK for the purpose of the Immigration.
However you would have to meet Maintenance and Accommodation requirements, which are more stringent for the National Law route than they are for the EEA route. As rightly stated by Ciara.
