DLTTEOAS is my all-time favorite Maiden song actually. I genuinely love every single song on that album, including TAATG, but I won't tell you that it's the best Maiden album. It's not. But it is my
favorite. Obviously the most important part and the obvious explanation is nostalgia. I grew up with that album, got into Maiden with that album and have countless memories that I cherish to this day connected directly in various ways to that album.
Overall I vastly prefer the 90s and and reunion era (with some outliers here and there) to the first 5 Maiden albums. I actually realized the other day, that if Maiden stopped with SSOASS I would've liked their albums and would still listen to that one in particular, but they wouldn't have become my favorite band. A lot of that has to do with Bruce's voice. He was always a fantastic frontman and could hit some insane pitches in the 80s, but could barely control his voice. He frequently overshot the notes he was going for, especially live, and basically wrecked his voice during the World Slavery Tour. The Bruce that I adore as a vocalist is the one from 1995 to 2008-is. That's his golden era.
TXF never properly clicked with me. It has some great songs on it, but its weak production, weak performances, brooding tone and dreary atmosphere ask a lot of the listener and I'm usually not in the mood for that.
While TXF's songwriting showed a lot of the tropes we would see in the reunion albums and could be seen as a prototype of sorts, VXI is BNW's songwriting twin (in my opinion). I've written about this a few times, but I genuinely believe no other pair of albums (except the obvious Iron Maiden/Killers pair) is as close to one another songwriting-wise as VXI and BNW are.
The latter obviously features four songs that were leftovers from the former, but even the other songs have similar stylistic choices. Most songs focus on melodic and repetitive choruses. The melody-writing on both albums is pretty similar as well. BNW has the obvious advantage of a phenomenal production and amazing performances. But as we've seen with The Clansman on RIR (and LOT

or Futureal released as a live B-side, the VXI songs fit well with the BNW songs in a setlist without feeling out of place.
