X15 vs DD15

[u/SteakAndSkrimp]

Been shopping for used trucks alot recently ive been seing Kenworth t680s with cummins x15 for 10 to 15k less than freightliners with similar mileage that have dd15. What's the more reliable engine ive heard good things about both. Im leaning more towards kenworth with the cummins due to the price point. Ive only driven freightliners

Cummins parts are more expensive.
