Deal of MSN and Yahoo is done – PPC for whom is better?

we came to know that Microsoft Corp and Yahoo Inc inked a 10-year Web search deal. If we want to invest our money for PPC Camapigns, which would be better option. Microsoft will be able to report a greater share in terms of search. So Bing would be platform to run PPC campaigns? or its better to use Yahoo as PPC platform? The Deal is not clear….Please help in this regard:confused:
