Paladin vs Purifier vs Shieldbreaker

Hello there!

Can’t decide between these 3 classes… I’ve only 1 char at 100 so I was hoping that someone with more experience can help me out?

Things to consider are:

-Tanky melee
-Uses both spells and autoattacks
-Caster off-hand as a stat stick, but a shield is also an option
-Fire, fire, fire

I like Inquisitor for it’s Seal, screen-wide devotion proc Word of Pain and Aura of Censure’s huge radius and RR, but recasting Word of Renewal is kinda meh.
Oathkeeper is nice for pets I get and Vire’s Might, also would use a shield too so I can throw it around and stuff.
Demo I just find alot of fun, mines are awesome now, Flame Touched and Vindictive Flame are just good for frontloading stats and Blast Shield can save my butt in melee, also I’d be using an off-hand here if possible.

So yeah that’s it, can’t decide which one, love all of them and since I plan to invest next entire 2 weeks into this character I’d appreciate if you guys could help me out.

Edit: forgot to mention devotions…

Fissure, Witchblade and Torch are main picks, rest goes into DA, res and other defensive stuff
