Well, i was pondering on the idea of trying Nexus, but i've read in most places that RSBot is just as good if not better, I'd just like to know your opinion.
RsBot is better. Although I did hear that Spelhojan stole the source from somewhere else, edited it and claimed credit. I don't know if that is true though.
Due to the fact that RSbot's free, there are more scripts available, and it has a great community which means you can get lots of help where needed. Seems like a plus to me :)
I believe that Rsbot is better, however it all depends on you. Both bots are great and work well in different areas/skills of Runescape. Experiment and you'll learn.
