I use an omnipod and I really love it. The lowest insulin denomination it goes to is 0.05 units, whereas other, tubed pumps go lower, allowing bolus and basal to be more accurate. And it delivers insulin in 0.05 amounts on a set timing that can't be speeded up. So if you are doing a decent bolus, it can take while with an omnipod.
But I have used a tubed pump and didn't find being connected at night to be an issue. I think most tubed pumps would need removing for swimming (? Not sure how many waterproof pumps are available). And you can get good pump belts to use while doing martial arts (and the rest of the time, if you can bolus by remote).
