Yeah, I think paladins are the top dogs in the current game; we'll see what happens next year. They are phenomenal tanks, reliable damage dealers who can nova like crazy, off healers with some interesting spell options that increase their versatility, have an aura that is arguably the best group buff in the game, and can even function as the party's face if it lacks one of the primary charisma classes.
Honestly, I feel the Paladin is a strong contender for the best class chassis in the game. Although it pays for this, because few of it's subclasses really wow me, but that could just be me.
Compare and contrast it's cousin, the Ranger, which flounders due to it's dubious identity, where the subclass has to do the heavy lifting- Ranger with a bad subclass is just terrible, while a Paladin with a mid subclass is just fine.
On the other end of the spectrum, we have the Wizard. It's class chassis is poor and pretty bland, even compared to other full casting classes, like the Bard or the Cleric. But because it's power isn't in it's class chassis, but in it's spells, a Wizard with no subclass at all can perform quite well (or badly) based entirely on your choice of spells. That's pretty horrible design, yet it persists because that's how the Wizard has always been, and if you change it, some people get irate, lol.
As an aside, the Sorcerer suffers especially from this, because spell choice is absolutely vital- if you don't pick spells that are always strong and useful, you're in for a miserable experience.
I mean, look at the Cleric. Here we have a sturdy class chassis with decent hit points, AC, ok weapon choices, Channel Divinity, and subclasses that ooze flavor and can grant potent features and spells that a Cleric can't even use. And if they pick a bad spell, no problem, I'll pray for a different one tomorrow!
So why does the Wizard get so much attention? Because most of the Cleric spells are fairly poor, designed to be silver bullets for specific situations. I've seen a ton of Clerics who are basically "healing word, spiritual weapon, spirit guardians, and some cool spell I got from my Domain", lol.
The dirty secret of D&D is that spell slots are not even between all of the spellcasting classes. A spell slot of a given level for one class can be less dramatic than one for another class. Which makes absolutely no sense, not just from a game mechanics level, but from a narrative one-
You're telling me the best spell a God can grant to their chosen champion is probably poached from the Wizard spell list? As the Hulk would put it, "puny God".
