Bitcoin is much easier to control.  And make no mistake, "regulators" do not want to regulate; they want control.  CN or US can establish BTC control if they choose, but I doubt that any other nation can establish control - although RU or IL or a few others could destroy it if they were motivated to do so. So far, they have not overtly asserted control. I don't know of a reason to expect that to change soon.

Monero is small enough yet to be easy to destroy for most developed nations, but also too small to bother.  By the time it is a target, it will be much more difficult to destroy because of the fullnode jurisdictional diversity, and Kovri tech.  More difficult to destroy than bitcoin, but effectively impossible to control, unless the core team is co-opted - in which case, the community will fork it.
