As far back as 7 years ago, the Blodget small PIZZA ovens were their 961P and 911P models. (P for pizza)

If you look at their website, the 981 is listed as a baking and roasting oven. I am not arguing what your experience may have been with Blodgett in the past . . . I am just stating what is here and now as options. The “P” models of the above models have three things in common . . . (1)rockite decks (fake stone); (2) higher thermostats 300F to 650F; and (3) a 30% higher BTU rating than the base models. The base versions have steel baking shelves and 200F to 500F thermostats. You will notice at the link I put above, the pizza ovens are the “P” models of the smaller ovens.
While BTU per square foot of baking surface may not be a scientific measurement of baking efficiency for pizza, it does illustrate where the deck oven models diverge.

BOTTOM LINE: the 981, 1060 and Y600 all accommodate six (6) 16" pizzas at one time. The Blodgett 1000 may hold 5 at once. Which oven(s) from above do you want to stick those 6 pizzas into at 7:30pm on a Friday night? That’s really what we are talking mostly about . . . peak performance. 981 @ 50K BTU just isn’t the same as even the 1060 @ 85K BTU. Under powered is “no bueno” at peak time. Heat recovery just cannot be under-valued when the oven gets opened and closed repeatedly, and 50K vs 120K is huge. AND those steel decks in the 981 don’t store heat anywhere near what the 1 1/2" stone decks hold onto.
981 is a fine oven that performed okay for me as a moderate volume pizza oven until I got my 600. Now the 981 does what it was engineered for . . .roasting and baking. (and occasional on-site pizza events)
