Two-Piece Iron Battalion vs Two-Piece Cruel Electrum

I run an off meta Aeon Soul build for trials and 6s for resist x3 and Rift uptime when playing solo queue. I crutch Iron Panoply for the heals and am trying to determine which two-piece would compliment the build, Cruel or Battalion.

I have seen mentioned in this subreddit that the Battalion tests to a constant +20 for handling and reload for primaries, which is a decent jump.

The Cruel seems to play into the Aeon strengths of giving additional handling, reload, target acc and flinch reduction when teammates die. Not sure if there is any data on how much the gains are with single and multiples, but it seems like it would have a very high uptime in 6s and uptime when needed in Trials.

Just wanted to hear opinions from anyone that runs either of these two piece combos with any regularity.

Thanks!
