The right/best pump is the one that’s right for you
@Lily123 Other people might have different needs and different priorities and preferences.
Think about your lifestyle. Write down the features of each pump and circle anything worrying or anything extra-good. Remember too that cannulas are very important and often neglected. It’s no good having the world’s most advanced pump if the crucial interface with your body (the cannula) is crap or doesn’t suit you. Personally I’d never go for a pump which didn’t have a choice of cannulas, and I’d never go for a pump that had cheapy or dodgy cannulas. Make sure your chosen pump fulfils all the criteria: good pump for you, good cannula choice, good customer service.
I’d choose the Dana out of those, as you probably guessed. You can get a cheap Android phone if that’s an issue. I don’t loop with mine.
