I'm sure either would be good
Those are the two I chose between, having ruled out the Insight.
I went for the Vibe, largely because I prefer the Dexcom and so when I'm financially able, I have the option of getting that for myself. I also judged that the Vibe was more robust (my opinion after reading many reviews), I preferred the Luer sets as they're universal, and I liked the intuitive menus of the Vibe. I also preferred the look of it.
Can you handle both pumps and see which you like? If not, try watching videos on YouTube and reading as much as you can.
As you read, identify what are the most important features for you.
They're both good pumps, so you won't go wrong whichever you decide to go for
