Initial page
Yahoo has very well organized structure. It is more than just stock markets. You have all aspects of finance world structured in top scroll down menu. Market summary even for major European and Asian indices. Top stories are excellently highlighted. On the other side. It has advertisements. And no possibility to be personalized.
Google offers nice sectors summary where the money flows. You have possibility to see your portfolio already on initial page. You don't see any ads. Now disadvantages. The biggest is top stories. It really misses the way how Yahoo can pick the most important stories and particularly highlight them. Next con, Google is here just for US indices.
