I think one reason for Bruce's "reserved" stage presence in 2022 (in addition to the COVID-era rust) was the nature of the Legacy of the Beast set, especially with the Senjutsu additions, as
@Vaenyr above already mentioned about the opening track. There weren't many songs in the set that didn't have him carrying some kind of a prop, or having other kind of "choreography", hence the timing of the outfit changes, appearing back on the stage, catching breath etc. was even more precise than on some other theatrical Maiden shows. The "Bruce's wardrobe" videos they put out at the time were particularly enlightening on that!
While I absolutely loved the 2022 set as well and still consider 2018 as one of their best ever shows & tour legs, it was also nice to see a bit more laid-back and relaxed approach to the show for the Future Past run. Bruce was particularly talkative and while those performances also had certain choreography, as you'd expect from a Maiden show, there was a bit more "just messing around" aspect to it all as well.

As for 2026 tour, I'm still over the moon on the fact that they're finally playing Infinite Dreams and it sounds
phenomenal, although I obviously wish that we could've witnessed Nicko & Steve handling the rhythm section there, their synergy in the original recording is absolutely iconic and one of the cornerstones of the track. Simon is doing great job, though! I'm very pleased with him.
Alas, I probably won't be seeing this one live myself. That sucks, but at least there should be a live video coming up from the show in Paris. I just hope that the mix is good.
