Every time I go through deep water or mud I'm glad that I have outer seals on my front end. They won't keep all of the water out but they keep it from rushing in.
I feel like if you are the type of person that pays attention to your Jeep, there's no reason to NOT use outer axle seals. I had a lower balljoint go bad which led to the inner seal failing, and the outer seal didn't hide the leak at all. If your axles are articulating much then the oil is going to get past the lower edge of the outer seal pretty easily. I can see it being a problem if your inner seals fail due to time and age, and if you're on the highway all the time or just driving through town maybe the oil level wouldn't get past the outer seal.
