Currently using Adbrite. Google twice banned me, suspiciously right before a check was due to be cut. Both bans were for no apparent reason. Other than I had been advertising my site. Advertising my site. hmmm, I didn't see that in the TOS.
Having used both I can tell you that on the whole AdSense pays slightly better. AdBrite does have other advantages though - for one you can use it on slightly risky sites, whereas you can't do that with AdSense. AdBrite also allows you to combine inlines and interstitials with their standard units, whereas you can't do that with AdSense either. A good choice would be a combination of AdSense for content and AdBrite inlines. Hope this helps. Regards Tehmina
I have got the best results from Adsense on every test I do, it's down to preference for some but I would stick to Adsense, follow TOS and optimize your ads for the best CTR.
adbrite ran out of ads the minute you joined and you'll end up giving free advertising space to adbrite. so obviously adsense is better.
i have been using both, but with adbrite there ads seem to time out and also display the same ads everyday. i had to disable the word over links because it just slows your forum down, so annoying. but i am going to leave adbrite on my site for a little longer just to test. and my answer is google by far.
