The prices you use aren't even close to my experience with United for upgradeable tickets with miles. I have never purchased a ticket class to Europe I could upgrade.

Clearly, the prices make a difference. If the upgradeable fare is too much, then a full award ticket is probably better. The prices I gave were those from the website or given to me by a res agent.
I'm just taking this as another tool in my bag, since, like most things in this airline world, everything is a case-by-case basis.
