I've used both Doodle and Calendly with my team here in the US, and honestly, it really depends on what you need. For group meetings where everyone's availability varies, Doodle’s polling feature is a lifesaver—it lets participants vote on times, which makes finding a consensus much easier.
Calendly, on the other hand, is excellent for individual scheduling or when you need more automation and integration with tools like Google Calendar or Outlook. Its round-robin and team scheduling features are great if you’re managing multiple people or client bookings.
If you’re specifically looking for ways to make group scheduling smoother, this article I found gives a really clear overview of appointment poll tools and how they can help US teams coordinate meetings efficiently:

Overall, I usually start with Doodle for group polls and use Calendly for one-on-one meetings—this combo covers most of our needs.
