Depends on what you're looking for. If you want an aftertreatment system which holds up well, Detroit Diesel does it best.. those are only available in Freightliner and Western Star trucks. Reliability of body components and interiors, probably Kenworth (if you exclude the issues they've had with water getting in through the clearance lights on the T680 and T880), plus they also have the most dynamic platform of them all with the C500 and T800. Peterbilts are nice, if you don't mind replacing rivets fairly often. The axles, transmissions, entire air supply system.. all of that comes from third party manufacturers (Wabco, Bendix, Meritor, Eaton-Fuller, Dana-Spicer, etc.)... Mack and Volvo are the only ones who offer proprietary axles and transmissions, and, in the US market, the latter is only applicable to the I-Shift transmission... manuals are still Eaton-Fuller.

Kenworth or Peterbilt, hands down the most reliable trucks from the US.
