Personally I've had very few issues with PingPerfect, running them (and continue running them) for years now, across multiple games.
As they use the common "cpanel" I find it easy to setup, to configure and get it to run, and support is normally very quick.
I would suggest checking out if any other hosting providers have free-trials (I know PP has a 48h), and try it out. However the cpanel UI is fairly common, and presumably everything works fairly standard.
What issues specifically are you having in configuring? When I setup a new PP server it probably takes me less than 5 minutes to configure, and start it up, simply using their tool for editing the serverconfig.xml file (that they label pingperfect.xml). I even run occasional weekend events when I stream, where I change up the settings to make it more of a challenge, and most of that time is noting down the OLD settings in wordpad so I can change it back afterwards
I even made a guide a year ago of how simple this was, where you spend more time listening to my boring voice than actually configuring a server, which says a lot considering it's a 20 minute video -->
(Full disclaimer, PP did partner with me a month or two back and is sponsoring a 7dtd server for me as a result, which was after 2 years of me paying for servers, which I still do for conan / ark)
