Hi.
I'm sure you've already made your decision by now but I can give a view on both.
I use the Omnipod and can say it's the best decision I've ever made. The wireless feature is a huge bonus, and I've found the multiwave (extended bolus on the PDM) to be extremely useful. It doesn't take long to refill a pod. Each pod can hold 200 units.
My partner has the Accu-Check Insight and that works for him. It has a greater option for increased or reduced basals in increments of fifteen minutes rather than half an hour for the Omnipod, and that's the same as the extended boluses for the time length too, the Insight is in fifteen minutes, rather than half an hour increments. The Insight can hold 150 unit cartridges.
I hope this is helpful
