Which is better, Xi 'an Social Security, Easy Social Security app or 5 1 Social Security app?

I've used both, and it feels similar. I just pay a social security fee, which is quite simple, but the social security fee is low, and the social security fee of 5 1 is high. I used 5 1 first, then changed it to social security decisively, and now I still pay it on it. I would appreciate it if you could take my answer. If you need anything else, you can ask, thank you!
