Thanks for the replies gents.

I guess I should link these for a side by side comparison.

The Bontrager H2 in 700 x 38

The TPI was what I thought was more important to ride quality. I'm not sure what Kenda uses for their "iron cap" flat protection. The H2 uses kevlar. I know the tread doesn't really help with anything on pavement, and may actually slow it down some.

Trying to learn something here. Will probably cough up for the H2's before long. Just trying to use what came on the bike a save a buck!
