The awesome level of power armour in Fallout 4 is significantly downgraded from before.
In Fallout 1, 2, and 3, you are a demigod in a power armour. In F:NV, ranger armour is a viable alternative to power armour (personally I prefer ranger armour because of the lighter weight). In Fallout 4 power armour in general is just shit because a) you need a power armour station to do repair, and durability is shit, but normal armour never needs to be repaired, b) as mentioned before, you need power cell to power up, even though power cells are plentiful it is a PITA to carry them around, especially in Survival mode).
So they are not really giving you leg up with an early power armour in Fallout 4.
