🔱 towelroot or kingroot? 🔱

Hello everyone, my laptop is terrible(almost dead at that) so I don't have general access to rooting through pc techniques. On top of this, I would rather not go through that process and instead use an on board rooting app. I tried towelroot (I use a SAMSUNG GALAXY A3), and to no avail. At first it gave me the phone not supported message, so instead I attempted to use the codes to do so. When I did, the make it ra1n button went orange and the application stayed in that state with no response. So I have a few questions.
1. Is there a way to fix this? I am trying to root fast so I can use the Xposed framework.
2. Is KingRoot a viable option? Is it as safe as towelroot, and will my phone data remain after using it? It seems safe, but I'd rather not take any risks currently.

Thank you for reading this, and thank you in advance for any help I receive.
