The catch
Ninja Woodfire Outdoor Oven
Neither indoor use nor Volt's 70°F proofing setting is something it offers.
Side by side
Woodfire OO101 is the outdoor oven that also roasts and adds pellet smoke. Volt 2 is for indoor pizza, dough-proofing down to 70°F and its 850°F maximum. Each fits 12-inch pizza. A compact peel comes with the selected Volt 2 Essentials bundle, and Ninja supplies a roasting pan and smoke accessories.
Before you buy
Down to 70°F is how low Volt 2's dedicated proofing mode goes, so it can handle the indoor dough stage and then serve as the pizza oven. OO101 starts its published range at 105°F and is meant for outdoors, which makes it no equivalent choice for low-temperature indoor proofing. Your recipe still sets the right fermentation conditions.
Where this comes from
Seventy sits 35°F under 105. All this shows is which settings are available. It is not a recommendation that one temperature suits every dough, and it promises nothing about fermentation speed.

The catch
No pellet-smoke system comes with it.

Woodfire OO101 and Volt 2 are compared on outdoor smoke, indoor dough preparation, temperature range and exactly which tools are included.
This one comes down to placement and published temperature span first, then to the limits of your own setup.
Which one fits
OO101 is outdoor-only, and Volt 2 is an indoor oven.

In practice
Down to 70°F is how low Volt 2's dedicated proofing mode goes, so it can handle the indoor dough stage and then serve as the pizza oven. OO101 starts its published range at 105°F and is meant for outdoors, which makes it no equivalent choice for low-temperature indoor proofing. Your recipe still sets the right fermentation conditions.
Seventy sits 35°F under 105. All this shows is which settings are available. It is not a recommendation that one temperature suits every dough, and it promises nothing about fermentation speed.
With OO101 you get the Pro-Heat pan, smoke accessories and a dedicated Smoke function. Its equipment therefore matters to anyone who wants a patio roasting and smoking appliance along with 12-inch pizza. Volt 2 adds indoor Oven and Broil modes, but the selected peel bundle is built around launching pizza and does not supply that smoke-and-pan system.
Included parts and named functions are the source of this distinction. It claims no measured difference in roast quality, and it does not permit generating smoke inside Volt 2.
Volt 2's maximum is 150°F higher, though both are rated for a 12-inch pizza. A higher selectable ceiling can matter for the recipe you want to follow, but it does not show that every pizza cooks faster. The bake times that Ninja and Ooni advertise rest on their own conditions.
The sum is 850 minus 700. It compares settings alone, without converting them into recovery time or throughput.

Ninja, OO101, Terracotta Red
This outdoor electric oven and smoker offers eight cooking functions and controlled pellet smoke. It does not reach extreme pizza heat.

Ooni, 12-inch electric indoor oven essentials bundle
This indoor oven gets very hot and adapts its top and bottom heat. It comes with handy presets and enough range to proof dough or broil toppings.

Trade-offs
Change of plan
Go with Ooni Volt 2. The indoor proofing and baking range is what Volt 2 provides.
Go with Ninja Woodfire Outdoor Oven. That combination of mode and accessory comes with OO101.
Decision guide
Go with Woodfire OO101 for an outdoor oven that roasts and adds pellet smoke as well. Go with Volt 2 for indoor pizza, dough-proofing down to 70°F and an 850°F maximum. Both fit 12-inch pizza. The selected Volt 2 Essentials bundle comes with a compact peel, and Ninja supplies a roasting pan along with smoke accessories.
The pizza diameter is the same, but these ovens belong in different parts of a household. Volt 2 suits an indoor pizza routine, while OO101 suits an outdoor cooking station with smoke and roasting. Don't move either into an unapproved setting just because both heat electrically.
If dough preparation is something you do repeatedly, the 70°F proofing capability of Volt 2 can matter more than its high ceiling. The OO101 has a lower published limit of 105°F and a different mode list, which suit other outdoor jobs. Plan either workflow around the recipe and the permitted range of the mode you select.
Ninja includes its pan and smoke tools, and the chosen Volt bundle comes with the compact peel. Do not assume either package list holds for every retailer bundle. Decide which items support the meals you will cook, and check for suitable pans and tools before treating either purchase as a complete kitchen.
