Quirlion requires you to register with the site. Which is worth it since its very easy to run multiple adverts using this bot. It allows you to run all of your bots on 1 screen, and when you minimize it, it goes to the tray.

Rsbot is the most experienced of all bots. This one does not require you to register with the website though so its a lot faster to set up. This bot is 1 bot per screen so running multiple bots can be rather difficult.
