They solve the same problem on different phones
Before these hubs existed, your step count lived in one app, your sleep in another, and your workouts in a third, with no shared record. Apple Health and Google Health Connect both fixed that by giving each phone a central place where health data can be collected and shared between apps, with your permission.
Apple Health is the iPhone hub. It is where Apple Watch data lands, and where apps like a running tracker or a sleep app can deposit their numbers so everything sits together.
Google Health Connect is the Android hub. It plays the same role: a shared, on-device layer that fitness apps, wearables, and health apps read from and write to, so the same workout or sleep record is available across the apps you use.
Side by side
Because these track the platform you are on rather than a free choice, the useful comparison is what each one is and how it behaves.

The takeaway is that they are mirror images on opposite platforms. What matters for your results is not which hub you use, but whether anything reads across the data it collects.
The honest take: your phone already chose
There is rarely a real decision here. If you have an iPhone, you use Apple Health; if you have an Android, you use Health Connect. Switching phones to get a different health hub would be backwards, because the hubs are close to equivalent in what they do and how they protect your data.
The decision that actually matters is what you connect on top. A hub full of well-organized data is still just data until something reads it in context. Wellness Project is built to be that layer on either platform, which is exactly why the iPhone-versus-Android question stops deciding whether you get useful coaching.
iPhone or Android, the coaching is the same.
