What song/album from Dream Theater did you fail to appreciate for the longest time?

I’ve been listening to Dream Theater for 20+ years now and I feel I ‘slept on’ Systematic Chaos. Been listening to it a lot this last week and absolutely loving it. The Ministry of Lost Souls is such a good song, and In the Presence of Enemies pt’s I & II are incredible. Was just intrigued what songs or albums from Dream Theater were like this for you?
