Why is MSN search Enginer better than Google?  Or why is Google's
search engine better than MSN

The best search engine would be:-

1) The one where you can get the search results you wanted, and where
your required search is nearest to the top of the list.
2) The MSN Search takes longer to load on my machine than google (so
in that way google is better)
3) The one that gives the highest number of relavent pages would be
the best (sometimes google gives the most results, sometimes msn - but
how relavent they are depends on exactly what you are looking for).
4) You may prefer the interface of one or the other (although the main
search windows are now fairly similar, but the advanced search windows
are different).
5) MSN search can search the Encarta encyclopedia from the main
window.  Google can search text of books (some of), and other specific
searches.
