>But I'm not sure this fallacy has a name.

I've also noticed it, and I've attributed it to the fact that the devil is in the details - you see all the intricacies and problems in the details of the solution you know, but only the shiny facade of the other proposed solution. It's basically the same idea conveyed by "The grass is always greener on the other side of the fence" - that's not a very handy name though.

Yeah, it's partially a grass-is-greener thing, but partially a fundamental failure to realize that you're allergic to grass, and even if the grass really is greener, that won't actually solve your problem.
