if 1 is a barren wasteland and 10 is GTA 6 on release, it's about a 3. Maybe a 3.5-4 when it's most active.
The problem with MCC is that it's really 6 different games and then from there a multitude of modes you can select to search for. So depending on what you want to play, you may be waiting for several minutes, or maybe less than 30 seconds. You can also check out the server browser but a lot of the servers host trash modes that are only alright if you're high or something. Competitive playlists are all almost completely dead. I don't reccomend even trying with them.
Stick to peak hours and party up with friends to increase your odds.
