Replying to Knee Brace: CTI vs. Donjoy

So my surgeons given me the ok to start skiing in a few weeks after 6 months of rehab on a patellar graft for my ACL. What im wondering is which brace is preffered by others who have been in my situation. My surgeon recommended the defiance from Donjoy, and I have been looking at the Defiance lll as well as the CTI Custom. I saw numerous different opinions on each brace in the various threads found on here. I'm wondering pros/cons and major differences between each brace and any additional info that may help. +k and mad props for anyone who can help!
