I agree however globally advertisers are used to AdWords and will surely have to find a viable alternative like BingWords very quickly to keep up their sales etc.

The preceding is about advertisers, and I don't see how they directly impact searchers? Maybe indirectly, but I don't see direct impact, or their revenue having anything to do with the search market share, the preceding stated:

If BingWords does not appear quickly and with good relevant ads they may find searchers reverting to Google or the user may actually have to search and how many know how to do that properly other than through ebay?

This one's an interesting point to me... And leads me to the question:

If Searchers need the AdSense Ads to find what they are looking for, how good is Google in the first place? Or, IOW: How much better is Google as a search engine for the average searcher than any other search engine if searchers have to have a supply of ads on the results to find the answer they were looking for?

Personally, I've used both, and have been using Bing for quite a while now and still find what I need rather easily, but I'm also fairly good at searching, so my ability to use either may not apply to most users, but I can say I have not changed my queries too much to find similar results. I don't always find the same sites, but I do find the answer I need within the sites presented by Bing as easily as I did with Google.
