Juno, We're facing the same issue. I was originally scheduled to have a bilateral with Dr. Gross in May, but "chickened out". I was afraid I wouldn't have a leg to stand on! After the surgery on my right leg, I am glad I chose that route. I am in awe of those who have both done at the same time, but I don't think I could have been functional as soon as I was.
I am walking 20--25 minutes cane free at 7 weeks post surgery, and the pain in my non-operated leg sometimes is worse than the operated leg, but also, the fact that I am not favoring the operated leg as much has also eased some of the stress on the non-operated leg so its a positive, but mixed bag.
Wish you luck and endorse the course you are choosing. Jeff
