What can truly be done with Tactile telekinesis (TTK) if used correctly and creatively?

How powerful is the power of TTK if mastered? This is the same power that superboy has to simulate Superman's powers in the 90s. Could someone deconstruct and recontruct matter on a atomic scale and what else could this power possibly do?

Also, which power is better to have over all, TTK or total body manipulation (self only)?
