There's lots of variables to 'feel' from stems.
Long story short, in my experience, all of them feel normal after you get used to it. Negative rise and more length makes the steering feel 'slower' and more stable to me. Shorter / positive rise, feels more sprightly.
Obviously there's going to be many different points between those 2.
I would suggest you identify what is uncomfortable. Too stretched out is different to too low.
Start by raising /flipping the stem, and then see how much shorter you want to go. Keep adjusting on the cheapest stems you can get untill it feels right.
