They're both really good passers, albeit with different styles - so it's like comparing someone like Casemiro wih Kanté. Pogba is akin to Falcão with his ability to not just pass well but dribble and shoot and go offensive box-to-box as a fairly complete central midfielder. Very Brazilian is spirit even though he's compared with Vieira - more of a risk-taker, and a lot of what he tries doesn't come off - but when it does the effect is spectacular because most players wouldn't even try something like that, regardless of them possessing the technique on the first place. Whereas De Bruyne is in the mold of someone like Günter Netzer at Mönchengladbach given the speed with which he triangulates the field ahead of him, guile and preciseness in terms of short passing and final balls - though without evidencing the crisp depth of space long range passing of the German, especially on cross-field diagonals - which probably makes the comparison an imperfect one. De Bruyne is a more effective player and fundamentally sound passer right now - cold-blooded on the edge of the final third, always scheming, and incisive like a surgical knife. He was really good at Wolfsburg too, but Guardiola has managed to fine-tune his game - elevating him to a higher level, and the Belgium operates like clockwork alongside Silva these days - seemingly making 9 good decision with every 10 touches of the ball - Cruyff would be a big fan of him. Pogba is younger, more of a flamboyant free-style player a times who's still a bit inconsistent in terms of his decision-making, so he wastes a lot of balls and time and potential space - but he has the talent to kick into a higher gear as he matures out of his oftentimes hit-and-miss style or if he works under an expert midfield coach. He might never reach the level of consistency of De Bruyne in the final third, the consummate rhythmic passing ability of Kroos, etc. but he has a lot more to his game as well.
