I use an omnipod and I love it. I do like that it's tubeless and can be sited anywhere with no outfit issues. The PDM is fairly intuitive and easy to use. Cons of omnipod would be the bolus increments: it only goes down to 0.05 units and other pumps go smaller and therefore the bolus can be more accurate, and the fact you can't adjust the time it takes to give a bolus dose - it drips it in in 0.05 units, seconds apart, so if you're giving a big bolus dose it can take 5 minutes + to complete.
I have also used a Medtronic and while it was a perfectly decent, again, intuitive to use pump I didn't really get on very well with it. I found it to be fairly clunky/bulky to wear and because you need to be able to access the pump itself to use the bolus calculator I found I couldn't wear it with dresses. Absolutely no problem sleeping with a tubed pump, which I was worried about, it just followed me round the bed, no bother. My main problem with the Medtronic was that I was using the 640 with cgm for the predictive low suspend and the cgm just didn't work well for me, I had a lot of issues with sensor failures and inaccuracy and I couldn't trust the system.
When choosing a pump my main advice would be to try and get your hands physically on the pump options available to you. Handle the, press the buttons, look at the screen layout, feel the weight of them. That should help you decide which pump would suit you best. Also have a look on YouTube for pump reviews and videos of people siting their pumps to help you see what cannula insertion options there are for each.
