Hey OP,

For Singaporean, there is no need for Family Visit Visa if you have no intention to stay for more than 2 months or your husband want to sponsor you for Residence Permit.
If I am not wrong, here with the difference:
- Tourist Visa given one months and extendable to additional month.
- Family Visit Visa granted you stay in the country up to 6 months. Additional, if you want to apply for Residence Permit, you don't have to leave the country during the change over of visa.
- Family Residence Permit gives you the right to stay here long term with your husband provided your husband meet the requirement as a sponsor. E.g. Job roles stated in employment contact, salary requirement & housing.

Hope it helps to give you an overview.

I might not be 100% accurate but should 95% there :)
