Perfect fighter runs alot smoother than Dreamfighter (Autofighter pro) and is more flawless but Dreamfighter has alot more options than perfect fighter. Dreamfighter is still in beta at the moment and you can use it for free. Not all the options work perfectly on it yet.
Here it is if you want it: 703Xz3HHFAW8Q2U68F
Dreamfighter is cheaper from oembots.com than it is from rsbots.net.
The extra options that Dreamfighter has that Perf's doesn't is:
- Level goals. You can set it to fight until a certain level in a skill such as attack and then make it automatically switch to say strength or something.
- Prayer usage: Burst of Strength, Chivalry, Charity of thought, Eagle Eye, Hawk Eye, Improved Reflexes, Incredible reflexes, Mystic Might, Mystic Will, Mystic Lore, Piety, Protect Items, Rapid Heal, Quick Prayer, Rapid Restore, Redemption, Retribution, Rock skin, Sharp Eye, Smith, Steel skin, Superhuman strength, Thick skin, Ultimate strength
- Escape from revenants
- Recharge summoning at Obelisk
- Rock Crab support
- Deathwalk
- Recharge prayer at alter
- Teleport on Emergency
- Rest at bank
- Denote food at general store
- Move compass randomly
- Move mouse randomly
- Clean looted herbs
- Drop looted herbs
- Teleport grab
- Check stats randomly
Overall I would go for Perfecticus fighter because it is flawless and runs smoother. This is a very nice bot but as I explained above it does not have as many options.
To answer your last question, yes you can add it to the autofighter.org client. All of the clients are exactly the same.
i shall try out this beta
