Hi, Ezekiel.

I don't think there's a magical suit. You can make any of those (and more) into something perfect for you.

A lot of it depends on your playstyle.

if you use chivalry spells all the time, totem of void would make sense, for instance. But if you're like me and only use chivalry to support bandages and sometimes to use other spells while not under fire, then primer of arms is good for the 20% damage increase and the ability to help make low-damage weapons (like soul seeker) better.

I love arms of battle excellence, but it's hard to make the resists work on a suit, so I only use it on my dexers mostly and not usually on my paladins.

Heart of lion is fantastic. But I do have ancient samurai do or vesper tunic and other types of tunics on various paladins, too.

If you have any or all of those, just go ahead and use them they're all good.

p.s. on shields, I like the 1/2 fc/fcr vesper museum shield or any shield that has fast cast and hci/dci on it.
