I picked up a new Apple Watch in September and went with the 10 after seriously considering the 9 and the current SE. I did wifi/bluetooth to avoid the additional cost of a data plan for the watch. The key deciding factors were:

• watch body to display size - 10 display is larger than either the 9 or SE
• Battery life - 10 has longer life
• Display - the 10 is easier to see and larger
• Weight - the 10 is slightly lighter than either the 9 or the current SE
• I went with the 44mm size and the Mrs went with the smaller version

I buy tech and use us for a long time so I buy at the head of the curve and keep things longer than most. this approach leaves me at risk at being phased out by Apple before the device stops working and I am OK with that. I'll take the seamless integration and functionality of the Apple ecosystem any day. I like the sleep tracking feature and the fitness motivation it offers.

I have installed the Garmin app on my phone and take it with me but don't worry about accessing it but have it as needed. Additional peace of mind when I’m out on the trails.

I'll be glad to answer any questions you may think of along the way.
