If by "friendliest", you mean most comfortable, the Boeing 747 in its Upper Deck Lounge configuration has the widest aisles, most leg room, and most comfortable seating. First class in a 747 is the equal or better of any existing passenger aircraft.
The crash of two 747 aircraft at Tenerife Airport in 1977 still holds the record.
The President uses a modified 747-400 when the President is not onboard it uses the call sign of VC-25A. But when he is onboard it uses the call sign Air Force One. The VP uses a modified 757. The same applies for the VP when he's onboard it is Air Force Two, but when he is not it uses C-32A. The VP uses the modified 757 on OCONUS (Outside Contiguous United States), but inside the US he usually uses a modified 737, known as the C-40 Clipper, or occasionally he'll use the C-37A Gulfstream. Hillary rarely uses a marked jet. She usually flies in either an unmarked gulftream, or she uses the C-37 or the C-40B, but when she travels with the President she flies on Air Force One, and when she flies with the VP she flies on Air Force Two.
