I think Servercraft would be good, it seems to do best for small community Minecraft servers. However, if you want a decent Minecraft server for you and your friends to hang out on, I would recommend the Tier 4 package which is $23 a month. If you're running a public server, you'd want at least Tier 6, which is $45 a month. Both packages are really expensive, I would just consider setting up your server to run with your home computer. You will need to set up No-IP(google it) to get a server IP, and port-forwarding, and you need to make sure your home internet can handle it(most home internet connections can't handle more than 4-5 players max) and you' ll want to run the server on a separate computer.
If you have any more questions, you can ask me.
