1.7
Music controls are weak because reviewers note missing phone playback control and limited direct playback.
contactless payments
Garmin Fenix 8
4.0
Contactless payments were counted as part of Garmin’s complete smartwatch-tool package in the supporting review.

value for money
Garmin Fenix 8
2.1
Value for money was the main concern: nearly every reviewer flagged the very high price, especially versus older Garmin models or narrower feature needs.

4.2
Value is broadly positive because reviewers see strong maps, battery, and materials at a sub-premium price, though one notes it is not cheap.
brightness
Garmin Fenix 8
4.3
Brightness was generally strong on AMOLED, though one reviewer tied always-on use to noticeably higher battery drain.

2.3
Brightness is mixed to weak: several reviewers found the MIP screen dim, washed out, or less clear indoors and under poor light.
smartwatch features
Garmin Fenix 8
4.3
Smartwatch features were broad and improving, but reviewers still framed Garmin as fitness-first rather than a true mini-phone replacement.

2.9
Onboard music storage exists and is useful for MP3 files, but reviewers criticize the lack of streaming support.
fit
Garmin Fenix 8
3.1

4.5
Fit evidence is positive, with the 46 mm unit described as the right size by one runner.
display quality
Garmin Fenix 8
4.5
Display quality was widely praised, especially the AMOLED option’s bright, sharp, colorful presentation and more attractive daily experience.

Coros Apex 4
4.7
Menu navigation is considered easy and uncluttered by reviewers familiar with Coros.
app ecosystem
Garmin Fenix 8
3.3
Reviewers saw Garmin’s ecosystem as deep enough to offer extra software, but weaker than Apple or Samsung for broader third-party app depth.

2.5
The broader Coros ecosystem is useful for analysis and route planning, but reviewers say social and third-party breadth still lags rivals.
user interface
Garmin Fenix 8
2.9
The user interface was the most divisive area, with some useful modernization but repeated frustration around complexity, lag, and unintuitive changes.
