Which Boots Should I Get

Hi guys, I'm just after a little advice over which hiking boots I should buy.
I have done a bit of light hiking before, just some day walks and such, but have now planned a trip to go to Nepal and hike there for about 10 days and so decided I needed to get some proper boots.
I recently ruptured some ligaments in my ankle however so I need ones that provide ankle support. After talking to the people in Mountain Designs and Adventure Travel they both recommended a different boot (because they have different stock). They both let me buy the boot and take them home with the option of returning within a month if I change my mind. And so I need to decide which boot I should keep and which I should return, which is where I need your help.
The two boots I bought were:
• Vasque Breeze GTX
• Mammut Impact GTX
So which would you advise I keep? I find both boots very comfortable and so cannot decide...
Thanks for your help
