I use both equally. I am lucky in that I am in Indiana, and both Summit and Jegs are Ohio companies. In fact, sometimes I will drive to the Jegs retail store in Columbus to spend some cash. In 2019, I also went to the big Summit store in Tallmadge to buy a Trick Flow top end kit. (i wanted to pay cash)

I think they are both great companies that have figured out how to survive selling speed parts in the internet age.
