If you and your partner have lived together for several years, there won't be a noticable diffrence when you get married except that you are officially a couple and is recognized by the law.

Now if you're asking wether which one is the easiest, after or before marriage. I'd say both are difficult.
You just have to appreciate that you have your partner going through those difficulties.

I would say if you could marry your right hand, do it. That would be easy I think.
