I think users’ experiences vary - it works for some and doesn’t for others. My son has been using OmniPod for 8 years. We’ve been happy. No tubing has always been important to us. I think there are pros and cons to every system, it’s just a matter of what’s important to the user.
I’ve written a couple of reviews - one is here.
I mention some common concerns that users have, but I cannot provide a comparative opinion as Caleb has only used OmniPod.
The Princess and the Pump has used both. As has Sugabetic Perhaps their perspectives would be useful.
