Three of the great Maiden tracks here. Hallowed is my number one song of all time by any artist. Seventh Son is a classic epic, and Greater Good of God is one of the best reunion era epics.
Now as for what remains....hard to remember what songs we haven't had yet without looking back so I would be just random guessing. If you want to give an update of the list so far I'll have a go at predicting the top 3.

I need to catch up a little bit! I'll capture the two most recent posts here and try to go back farther at some point soon.
The most recent post is absolutely superb. These three are all absolutely top 10 songs, songs that any band should be proud of having released only one of. And yet they released all three of them, and a number of others that equal them or come close. I agree very much with your description of Seventh Son as majestic. That's always been what I've liked so much about that song. It's so grand.
As for the post right before that, Starblind is another superb choice, definite top 10 song. You pointed out many of the exact aspects of it I'd call my favorites: Bruce's lyrics, H's jazzy playing, *that* riff. Great choice, great description. The other three are very good Maiden songs; I have genuine affection for all of them. Just wouldn't place them this high. I don't think I've ever heard the Beast Over Hammersmith performance of Phantom. That release is so hard to find.
On guessing the top three: I would also benefit from a single-post recap of what's been listed so far.
The best bet for listening to Beast Over Hammersmith is to look up the individual tracks on YouTube and listen to it there. That's how I always listen to that particular version of Phantom of the Opera, as I don't own the CD myself and it's not available for listening on streaming platforms.
And yeah, it's a testament to just how incredible Iron Maiden's catalogue is that there's so many incredible songs that are all worthy of being seen as all-time greats and so many fans have different tastes to what they prefer from the band.
