Outsider here so hopefully not butting in, but I definitely don't think there's any chance Columbus even thinks about Michkov. I don't think they're confident they can bring him over and/or make him happy. For them it's probably Carlsson or Smith IMO.
I think the Sharks might be a different story. I think a California team that can afford to wait for him like the Sharks can is a perfect fit for him. However, if Columbus takes Smith SJ might go for the center in Carlsson, and under that scenario it's you guys that have the real decision to make.
Personally, if I'm Montreal I take Michkov if he's available. I'm confident in my org's history with Russian players, I'm confident that my city is a hell of a lot more European than a random America city, and I'm confident that by the time he comes over my team will be in need of a potential star player on an ELC...and he'd be by far the BPA at that spot. I'd WAY, WAY rather wait for Michkov than overdraft a Reinbacher just because he fits a need in your organization.
