I would rather have Bernier than Bob over the long haul. Just simply because Bobrovsky' future is so questionable witht he KHL always looming. Plus, he still plays for Columbus and I know he got it done last year, but I need to see more.
Anderson is a better option for this year, and possibly next. But, it's anyone's guess where he goes next. I could see Ottawa anointing Lehner the throne when Anderson' contract is up. And, depending on how he plays over the next year or two, it will dictate his next role.
With all this being said, I think Bernier has enough upside for you to stand pat. Especially because your other options come with just as much risk, and not as much upside.
