I think the important thing in choosing an EMR is finding one that works how your brain works and makes your life simpler. It's different for different people.
For me, I wanted to be 100% paperless and I wanted everything integrated. I write really detailed notes and patient instructions so I needed something that would have good templates and would make the instructions as simple as possible. And I have no staff so needed a robust patient portal. I also am a tinkerer so a smaller company that would actually let me make suggestions or would customize things how I want them was nice icing on the cake. So for me, MD-HQ was the perfect fit. But again, that's me.
I think choosing an EMR is a lot like a dream house. You make your list of non-negotiables and your nice-to-haves and you try to find something that works for how your family lives. We needed a big dining room because I'm the oldest of seven kids and host most of the big family gatherings. My sister barely cooks and hates having people over so that wasn't a priority for her.
Make your list and look for what suits you best, not necessarily what anyone else recommends.
