Pearson's side are waiting to taste defeat this season and boast an identical record to that of Leeds - two victories and a draw.
He watched his side struggle in the first half but they were comfortably the more attacking side after the break, with Chris Wood's effort that rattled the post their main return.
"I think it was always going to be tight," Pearson said.
"Leeds came with a decent game plan and tried to limit the number of chances we had. We had the best clear-cut chances but we were unable to take one.
"I thought it was an interesting game with two decent sides who cancelled each other out. It was a decent game and I felt comfortable throughout.
"You credit Leeds for how they went about the game and that was how games are in the Championship - very tight and there for the taking."
