A front-facing screen (in addition to the main rear screen) is a feature that divides opinion.

Where a front screen is useful:

- Vlogging — you can frame yourself while recording, ensuring your face is centered and in focus

- Selfies and group photos — you see the composition before pressing the shutter

- Checking lighting on your face while recording outdoors

Where a front screen doesn't matter:

- POV footage (helmet, chest mount, handlebar) — you never see the camera while it is recording

- Action shots mounted on equipment — the camera faces outward and no one is looking at the screen

- Time-lapse — the camera is stationary and unattended

The bottom line: If you plan to be in front of the camera (vlogging, presenting to camera), a dual-screen camera is worth it. If you are primarily recording what is in front of you while doing an activity, a single rear screen is sufficient and typically costs less.
