Honestly, the best ones are located on HabboArchive, there's only 5 of them so why not try them all? Anyway, here's my opinion;
Kristal Panel - By far my favorite, the layout is professional it offers a great system and is pretty easy to learn how to use.
The House Keeping Guy - Good, but from my experience not great, although it does add a lot more features than some of the other panels.
Radio DJ Panel - I've used this the most, it's quite basic so you should be able to set it up and use it quite easily, got the same basic features as every other panel though.
I haven't tried the others, but they look awesome as well. Good luck :-)
