IMO the biggest bang for your buck would be the Coros Pace 2. It's honestly the best running watch out there and the app is super helpful all while it costs the same as the cheapest Garmin watch (Garmin 45/55). Though Garmin is also pretty good respectfully because I've had experience with it, the Coros is just amazing with its features, app, battery, gps system, and how smooth it runs. Best option for ~$200 is the Coros by far.
