Hi, I don't have experience of either of these pumps but I am using omnipod dash funded by NHS greater Glasgow & clyde. My only negative thoughts are it struggles to stick during hot weather & kept falling off; a lot of wasted insulin & pods. As you only use fast acting insulin it is extremely reactive so need to be careful with food types, would be good if you're pump had an extended bolus tab, I have found this option brilliant (reduces food spikes). Now using a pumo hot weather drastically reduces my insulin needs which didn't occur when using pens. Also if you drank alcohol the night before you should reduce your temporary basal rate. Hope this helps
