Generally I subscribe to the idea that 100% live is always much better than using overdubs. It is also better to try to rearrange songs before you decide that a backing track is a must... Playing live starts to lose its point when you try to make an exact copy of a studio version no matter the cost. What's great about Maiden's live recordings is how different they can be - not only compared to the studio take, but also to other live performances of the same song.
However, I have to admit that I changed my tune a bit after seeing Altar of Plagues last year. They used a lot of pre-recorded stuff - including all the bass (the band consists of just 2 guitarists and a drummer live). And you know what, it sounded freaking amazing. The sound was crushing and I think it wouldn't be possible to achieve 100% live in that environment (or at least would be very difficult). Take a listen if you're interested: https://altarofplagues.bandcamp.com/album/live-at-club-colectiv-bucharest It's their live album from that tour. As I said: 2 guitarists (very simple rigs) and a drummer - the rest is samples. Of course, the sound makes a much bigger impression live, but you can hear how the set worked.
What sucks about samples in the live environment is that usually you have to play to the metronome in order to use them. You're basically locked within song's boundaries and can't get carried away, which certainly would be very limiting for some bands. So it all depends on what you play.
