I think full body workouts ARE good for a pump and are also good for gaining condition.
With a split routine though, you can make gains in size and strength.
Have you ever noticed when you break your bounders in strength, for example complete a heavier weight in Bench Press or Squats or Dead lifts, you are very sore for days after and the recuperation time for recovery is greater.If the body is not given a long enough period to recover form these barrier breaking workouts you simply do not get stronger and bigger.
I think that with your full body workouts you are getting a nice pump and are feeling fuller on a daily basses but this will be at the expense of strength and size increases in the long term.
