It depends what you are looking for. I have been married many years to a Thai National (and unfortunately recently widowed...)
Not that I was looking for particular advantages, the things I've done through the years:
- you can have a Thai Spouse visa which allows you to stay in Thailand (I had a work-permit, but I am not 100% sure this is required)
- when I needed administrative paperwork to be done, being married makes it easier as your marriage certificate can bring more credit to your application: getting credit card (there are other ways, easier if you work), apply to life insurance, yellow book house registration, driving license
Additionally, your spouse will have an advantage to apply for visa to go to your home country.
