No sane pilot would fly an extra hour in a twin with a failed engine if it's not necessary for safety (e.g. weather and runway length are considerations, the rest isn't really important in case of an engine failure) The plane doesn't just fly nicely with one engine, it will yaw and become much less stable. You will also usually be descending (drift down procedure) because the single engine service ceiling is lower than normal cruise. And the autopilot doesn't work so you're flying manually, for all of the diversion. You really don't want to be doing that any longer than necessary. You have also no redundancy left, so continuing means you're increasing risks. Even more so because you'll increase your remaining engine to max continuous power stressing it more than usual.
