I use both. For the most part I stay in Numbers but for other many things Excel on the Mac is still better then numbers. For example, Quickbooks will export reports directly into Excel but not into Numbers. Also the 'Text to Columns' feature works better in Excel then in Numbers. In general I think Excel is a more powerful program then Numbers. However on the Windows side Excel beats both mac applications hands down.
