i would take kennon over marcos highway anytime when i am in a van or suv. but it's hands down marcos for me when i am in a car or a motorcycle.
Share mo naman ang reason/s for your preference.
When I was a bachelor kasi, and driving a car,- Kennon Rd. palagi ang daan ko. But now, with a family, and driving a van,- Marcos HW na (probably because it is safer and I am more patient now). TIA
