You are comparing an invasion to an invasion plus an occupation, which makes no sense. Saddam had a very powerful army at the time, and the US military walked through it like it was nothing. Occupying Iraq and building a new regime went terribly, as almost all such projects do. Even if Russia manages to conquer Ukraine entirely, which is a massive if, I've seen absolutely nothing in the past 6 days to make me think that an occupation by them would be anything other than a horrid disaster. Aside from pure propaganda, I have no idea what information you could be looking at to come to the conclusion that Russia is executing the invasion well at this point.
