I am having a tough time deciding which Apple watch to get, I keep going back and forth between the Series 9 and the Ultra 2. I currently have a series 6 that I bought brand new when it came out and the battery capacity is now at 82%. It is also only GPS and I would like to upgrade to a watch with cellular. I originally got the watch at the recommendation of my electrocardiologist for the ECG abilities and I use the health features regularly.
So again, the reason for upgrade is a watch with cellular, but I would also like a better battery life. I am a fairly small woman, and my series 6 is the 44 inch sized screen, I think I could handle going up to larger sizes though. I am not an outdoorsy type of person and when I exercise it is nearly always indoors but I am a little bit seduced by the better battery life of the ultra 2 - especially since I want a cellular watch this time. However, I have seen conflicting information as to whether or not the health data is better on the series 9 or the Ultra 2.
Anyway, this is all to ask, which would you all get? Below is a pic of my current watch on my wrist. Thanks!

Have you thought about a refurb series 7? You get your quick charging, it doesn't look massive compared to the Ultra and when you look at price, it's £799 vs a refurbished Stainless Steel model for about £260. Check out eBay for companies which offer 12 month warrenty with it too. I got quite lucky with mine, I got 20% off bringing it down to £210 and I have the option to renew Apple Care.
You seems to be able to get way more value with the Series than the Ultra. Not to mention, you probably won't sell your S6 for much so you can use that for sleep tracking while your S7 is on charge.
Back onto the Series 9. In terms of health tracking they have the same metrics but Apple Watch Ultra is a little less accurate when it comes to HR data due to the size and weight of the watch.
