For a disposable pullup, I recommend the NorthShore Care GoSupreme Pull-On. I have used cases of these pulups. Although I normally use taped diapers, there also is a time when pullups are appropriate.
Pullups are great for medical appointments where you may have to remove your diaper. My dermatologist checks ALL my skin, even under the diaper. A pullup makes it much easier.
When I wear a pullup out of the home, such as to a doctor's office, I usually also wear a PUL diaper cover.
I have tried several pullups and the NorthShore GoSupreme seems to be the best for me. It is more absorbent than the competition and has both good leg gathers and internal leak guards.
