Which one-Canon 15mm 2.8 or Sigma 14mm 2.8

[buffalophotographer]

I bought the canon 15mm when the double rebates was offered and just today bought a used Sigma 14mm. Which one in your opinion is the better lens. The sigma is significantly a more expensive lens compared to the Canon 15mm. Whcih one should I keep?

Thanks
