Oh, and heavy armor for the Paladin.
A rage doubles your durability and healing done to you. Suppose 12 con; then a Barbarian has 13 HP, possibly times two, and possibly doubling healing. The Ranger has 11 HP, 42% of the Barbarian's durability before healing. If you include HD healing, that is 41 HP vs 17.5, same ratio.
The adventuring day/XP required before level 2 is tiny, so you are going to be raging in the vast majority of challenging fights before level 2.
When raging, the barbarian has top-notch (level 1) damage output. Ranger's have baseline martial.
Barbarians also get the unarmored defence ribbon feature, which is about as useful as both of the Ranger's ribbons combined (ie, not very, and if so, very situational).

For the Paladin, you get divine sense, which is a better situational ability than both of the Ranger's abilities combined.
Plus LOH, which brings the 12 con Paladin from 17.5 HP/day to 22.5 HP/day, or can be used to save a downed ally in smaller pieces.
