Honestly, the jury is still out, and it really comes down to personal preference because these two websites are virtually identical. Both companies provide the same service in credit monitoring, the same advice on how to improve your score and maintain it, and similar offers in a similar way, even if they’re not the exact same financial products.
The only meaningful difference between the two is that Credit Karma gets its information from Transunion, while Borrowell gets its info from Equifax.
This is significant because both credit bureaus calculate credit scores and reports slightly differently, so if you’re a member of both websites, you may find that your credit score on Credit Karma is different from your credit score on Borrowell.
This is nothing to be alarmed about and on average you will get approved for the same products no matter what bureau the lender in question pulls your credit file from.
