I've had Omnipod for maybe four months now and I love it! It's my first pump, so I can't directly compare, but the idea of being tubed was a bit horrifying for me - as well as the general inconvenience of constantly carrying the pump around, I *know* I'd be catching it on everything!
I mainly wear my pods on my arms - it suits me really well - I barely notice them. I bash it ALL THE TIME, but haven't managed to dislodge anything yet, so no worries there.
I also occasionally wear it on my lower back if I don't want it on my arms for whatever reason. I don't love it quite so much, but it works ok and is surprisingly unobtrusive.
I haven't really managed to make tummy area work at all - it's in the way and inconvenient for lots of stuff that I do, so I just don't use it.
Some people seem to like legs too, though I've not done much yet.
Not quite CGM (though if the fabled Omnipod/Dexcom integrated whatnot ever transpires, I might well give it a go), but I'm also using the Freestyle Libre which, with no exaggeration, has completely changed my diabetes life - I'd recommend it to anyone!
