Is dipping X levels in War Cleric worth it after Paladin 6 or 7?

I just leveled up to Paladin 5 and was wondering if dipping any levels in War Cleric after Paladin 6 would be worth it?

I have Wisdom 14 and can multiclass at level 7

For Example dipping 3 levels gives Paladin 6 > Cleric 3 > Paladin X

What I think would be Pros: More Spell Slots Access to 2nd Level Cleric Spells War Priest Can Attack Action 2 times for 2 rounds 2 Channel Divinity Uses for Cleric Options

Cons: Reduced health by 6 points Delay 3rd Level Paladin Spells by 3 levels Can't Get Level 20 Class Feature for Paladin Big Overlap of Paladin and Cleric Spells

But I also heard that Spirit Guardian at level 5 is a great Cleric Spell and War Cleric level 6 give free Shield of Faith
