I have both. So I definitely do not think the OP is crazy if they want to go with the SE over the 7. I absolutely love the form factor of the SE compared to the 7. If you don't watch videos or do much gaming, the SE is a fantastic little device. I do miss 3D Touch, but it definitely is not a deal breaker.
Why did you keep 7 if you love SE? Don't mean to be incriminating just curious
My 6s plus collected dust for a while, and then I sold it and got a 7+ and paid price difference, I like having latest tech. And a phablet and a mini phone. Both feel odd but awesome haha
Had a 7 briefly. Grew bored and disappointed battery was way worse than SE that it had temporarily beencsuccesor to
