I have tried Mint, Moneydance, and Yodlee. While they differ in look and feel, they are similar. I found that they are all budget-based as far as features. The aggregate your investment accounts in one place but when all was said and done, none of them was better for me than Vgds site, especially if you track outside investment there, too.
Google Spreadsheet (I like their "=returnxxx()" and other finance forumulas) does the trick for me. I'll check these other companies for more robust portfolio features as they mature.
