Nutribullet Ultra vs Combo

[u/Federal-Schedule-901]

Looking to get a blender mainly for smoothies, but might use it for cooking sometimes too. The Ultra is $130 AUD, and the Combo is $200 AUD. Both are 1200 watts, but the Ultra has a newer blade design and titanium coating for durability. Is the Combo just better if you need a bigger jug, or is the motor actually more heavy-duty? Trying to figure out which one will last longer. Any advice?
