I am convinced by the fact that some premium bots are better then other premium bots while some premium bots of the same premium client would be better at other scripts compared to other premium bots if you get my drift.
Autochopper CS simply sucks (which im gonna get rid of soon) imo while Autochopper pro (rsbots) is so flawless id be comfortable letting it run for 48hours.
As for the miner, autochopper CS is really the best, while the chopper of the same client actualy sucks ass. Well, it doesnt suck, its completely antiban still, it just matters on where you start your script as this autochopper doesnt completely support all places (edgeville for example at which it fails badly)
It can run 48hours non stop, solve 10 random events in the process and has no suspicious misclicks whatsoever, even under massive lag.
What bot to buy depends on what skill you wanna bot on.
But overall, rsbots is one of the best premium clients
