WalletHub is wading into the great bank versus credit union debate.

In a press release announcing its new web-based comparison tool, the consumer site touted credit unions as a better deal for people looking for a checking or savings account (and cited its own "Banking Landscape Report").

Saying it aims to "level the playing field" between banks and credit unions, the website said its tool would allow consumers to compare the best rates on checking and savings accounts within their set parameters.

"Given that credit unions offer checking accounts with 10-times higher interest rates than regional banks and savings accounts with six-times higher rates than national banks, the disparity in market share obviously has more to do with consumer misunderstanding of their eligibility than the competitiveness of credit union product terms," WalletHub said in its press release.

But given that banks enjoy the lion’s share of the market anyway, it remains to be seen whether WalletHub will make much of a dent.
