What is the difference between these two?

I already have Traffic in one room which is unstained white birch. The guy that I had finish it did not use the presealer, and did two coats of traffic. It's beautiful, but I can still feel the grain. Can I fix this with another coat of Traffic?

Also, I'm installing another floor in a different room that connects with this one. Is Traffic or Mega better? And if I do Mega, is it going to match the room that is already finished?
