I have been told by a few people that AF confirm adapters are inaccurate and harmful to use on your camera. Others say they help focus quite a bit. Right now I use cheap chipless adapters. Would it be worth getting a chipped adapter? I still struggle with my hit rate on my faster lenses.

I find them "spotty" - although on the whole I would rather have one than not. On the Canon the problem really comes if you are using the chip for exposure as well, and that is definitely inaccurate.

I tried chip adapter for a long time, bought a few different types (mine were m42-canon adapters) from different sellers. In general they didn't really help - I found that with the fast glass, the adapters were making me front-focus more often for some strange reason.
Now I just use the plain metal no chip adapter, use focusing screen, and practice, practice, practice! Practice make my hit rate heighter and train your eye better. Even with new DSLR with smaller viewfinder, it possible to train eye to see focus snap better.

At times it might not be accurate as it is designed to work within a certain range - tolerance. What do you mean by harmful to the camera? I have not hear nor read about this.

The benefit comes from exposure accuracy at least you do not have to
worry about EC all the time. Focus accuracy is iffy, if you have good eyes
and a good focusing screen, this is far better.
EC = Exposure Compensation

I got one of those programmable dandelion chip, and I use it my canon 1KD.
Every time I take a shot, i keep looking out for the little red dot flicking on my view-finder and that light beep sound. I realize that I have mentally lost focus on taking my subject. 
IMO, the AF chip is a tool that assist us get close to sharp focusing. We still have to train our eyes to look through that little view-hole, and not to loose track of the subject.
Constraints are that it work ok with manual aperture setting of >F5.6, and need to compensate for over-exposure. Good if u are taking (bokeh) portraits.

I am not sure about that in every case.
I have got (or rather "had", I have thrown it away) an adapter that caused a very high pitched sound in my EOS 350D. That did not sound good and I was afraid of destroying something. So I've never used it again.
And I often have the case that an AF adapter causes an ERR99 or ERR01.
I hardly use them nowadays...

It is indeed... and the standard 'kit' Vario-Elmar is no slouch for an AF lens either! Only sad thing is the rather dim viewfinder.. but I LOVE mine!

Some people seem to have had problems while others don't, and this might be a case of a cheap/bad AF-confirm adapter sample, but as with LucisPictor's case, similar horror stories have been documented:
http://reviews.ebay.com/CAUTION-AF-Confirm-Nikon-Adapter-for-EOS-cameras_W0QQugidZ10000000002548592
I have understood that Canon cameras disable both visual and audible focus confirm if it sees a broken lens circuit. Nikon cameras lose the audio but still see visual since it is the sensor seeing the light and not the AF chip :)
Personally, I don't trust the confirm audio or visual anyway, since even with misaligned AF lenses the focus might be off and the camera would still fool you into thinking you've got it right - and only afterwards on your computer you would notice if's way off or back/front-focused. With my M42 lenses and the D80 body it's even more way off, so I just concentrate my eye and learn how each lens behaves with the trial&error way.

I'm an AF confirm adapter user. I have 3 and they're also the new programmable type.
I've had no problems with mine. A sample from my Tamron Adaptall SP 90mm macro - a superb lens by the way. In this shot, i had a 2x TC on as well.
