I currently am using a Canon 70D with EFS 15 85 and EFS 55 250. I have been looking for a wide angle lense and am considering the Canon 10 18 and 10 22. Could one of you more experienced photographers provide some insight?

The reviews have me leaning towards the 10 18. I can buy a refurbished from Canon for $234 plus tax or $279 for new one at B & H.

This will be used primarily for landscape and garden shots at Hershey and other gardens. I am also hoping it helps in low light situations.
