Not really, it replaces the attack stat with the spellcasting stat, kind of like shillelagh but only for a single attack, and then stacks some radiant damage on it at higher levels (+1d6 from level 5 then cantrip leveling). It can also replace the damage type with radiant. Useful for any weapon-using caster class that doesn't get multiattack:
Clerics would be a great target audience for this, except it's not on their spell list. *sigh* Magic Initiate (Druid) it is.
It could be useful for non-hexblade warlocks too.
It's a great damaging cantrip for bards who severely lack those.
It's good for even a sorcerer or a wizard, it turns the light crossbow into a long-range radiant-damage cantrip.
Arcane tricksters: could be useful depending on the build, probably pairs really well with a headband of intellect. (Edit: Or an extremely INT-focused Arcane Trickster with a 2-level wizard dip for the bladesong.)
Eldritch knights: really useful at levels 1-4 if you're running into some monster that resists or is straight-up immune to nonmagical damage. Markedly decreases in usefulness once you get multiattack and/or a magic weapon.
Probably good for artillerist artificers (they are not in the UA so it's unknown whether they'll get this cantrip), might be good for alchemists, OK for battlesmiths until they get multiattack, and redundant for armorers.
How I'd improve it further:
Make its casting time 1 attack and limit it to once per turn in the fluff. That way it stays useful for eldritch knights, bladesingers (scratch that, bladesingers can cast this in place of an attack already), valor and swords bards, and the two multiattacking artificers (less so for the armorers, but even then, it gets them a good ranged attack in a guardian suit or a good melee attack in the infiltrator).
Add it to the cleric spell list. They are the full casters most likely to go into melee even without the multiattack.
That's only for the blaster-caster subclasses though. The subclasses that are more likely going to go into melee (mostly the ones who get heavy armor proficiency: Forge, Life, Tempest, Twilight, War, and many other subclasses) get Divine Strike instead. So a cleric build that takes 8 levels of the subclasses that get Potent Spellcasting would be unlikely to use True Strike by then, they'd likely hang back and spam Toll the Dead or Sacred Flame (or a ranged spell).
(Even with a heavy crossbow (that most blaster clerics aren't proficient with, but they can gain proficiency from racial features or multiclassing), at level 8: True Strike + 20 WIS + Potent Spellcasting = 1d10 + 1d6 + 5 + 5 = 19 average damage with +8 to hit; Toll the Dead + 20 WIS + Potent Spellcasting = 2d8/2d12 + 5 = 14/18 average damage with a save DC of 16. Not very much more powerful. And then you get to level 11 where TTD with Potent Spellcasting jumps to 3d8/3d12 + 5 = 18.5 / 24.5 average while True Strike with the heavy crossbow is 1d10 + 2d6 + 10 = 22.5. The cleric will more than likely spend the first turn setting up a buff/debuff/control spell, so the d12 damage dice will apply most of the time.)
Explanation so I don’t have to look it up please
True strike givs bonus to attack based on spellcasting stat

I suspect that's why it's not on their list.
