Buy an Apple Watch Ultra 2 if..
Apple Watch Ultra 2 features the largest and brightest display in an Apple Watch which makes it a great smartwatch for outdoor excursions, especially during the day to display your metrics and other information at a glance while hiking, fishing, sandboarding, marathons, and other activities.
Furthermore, it delivers longer battery life and exclusively offers support for recreational dives up to 40m for extreme water sports enthusiasts.
However, it is nearly 2x heavier than Series 9 models and its 49mm size might not be a good fit for all especially for people with slim wrists like me.
Thus, you should buy an Apple Watch Ultra 2, if you have over $700 budget, love extreme sports, and can carry the bigger and heavier smartwatch.
Buy an Apple Watch Series 9 if..
Apple Watch Series 9 is durable, offers good battery life, and features almost the same health, emergency, and navigation capabilities as the Ultra 2.
Series 9 is ideal for users who want the latest features but at an affordable price. It is lighter than Ultra 2 and comes in two different sizes to fit a wider range of wrists, alongside a range of colors and a selection of two materials: Aluminium and Steel.
I will advice you to visit your nearest Apple Store or retailer and try on the new smartwatches to see how it looks on your wrist before purchasing one.
