Yeah.I personally think it should be stronger at... whatever they focus on. The metabolic should be an A tier shapeshifter/self buffer, beating out the druid.
Versatility should have a price. Honestly the wizard should be the B tier at whatever they want to do because they get to change what they can do after a nap. The swiss army knife should never be the best tool.
My first impulse is the psionic should be best at mental effects. But then, telekinesis isnt mental but is especially psionic. And then the concept that thoughts can transform the physical body is an important trope in my culture, whence healing and shapeshifting.
Even the themes that I feel are least psionic, turn out to make sense with the right flavor. Like, undead. At first glance, not psionic. But what is a ghost if not a disembodied mind, or a poltergeist if not a telekinetic? While they exist as a shadow creature, it is their mind that refuses to rest. Meanwhile, "psychic" spiritualists that sense ghosts. Indeed, Pathfinder dialed the undead flavor to blaring.
Ultimately, the psionic is best at whatever ones mind focuses on.
The psionic excels in anything, it doesnt excel at everything. The price for the specialization is having less access to spells outside that focus.
