How is your camera compared to a Model 250 Land camera, Godfrey? My 250 Land is a rebuilt and fullly working camera, with a close-up kit and it used AAA batteries.
I'm not entirely sure I know what you're asking, Raid.
With respect to design and specification, they're rather different types of cameras. The Polaroid Land Cameras are pack film cameras, typically like a folding press camera with rangefinder focusing. The Polaroid SX-70 cameras are integral film cameras, folding SLRs.
You generally don't need a close up kit with the SX-70 type cameras because they focus down to about 8" with no attachments. I do have a close-up lens (and both wide and tele lens extenders); they're only needed occasionally, but fun to use nonetheless. The SX-70 type cameras require a battery; a fresh battery is part of every film pack.
Here's the original SX-70 promo advertisement:

If you're asking, "How do they perform?" ... Well, both perform very well, but they produce very different results. The pack films are sharper, crisper, more traditional looking photos. The integral films have a look all their own due to their process chemistry.
I like both, but I prefer the integral film cameras as they're easier to carry and use, have less materials wastage associated. But if your preference is for traditional values of sharpness and clarity, the pack film cameras are the way to go.
The sad thing is that Fuji has discontinued all but one (100c color) film for the pack film cameras, and Polaroid stopped making pack film more than a decade ago. Only Fuji knows how long they'll continue making the one film they still do. So when my stock of 3000b and 100c films is gone, the Polaroid Land 350 I have becomes a shelf ornament.
The Impossible Project is continuing to push new film formulations for the SX-70, 600, and Spectra type integral film cameras. With luck (and enough sales) they'll stay in business a good long while. I'm sure they won't last forever either, but I'll enjoy the cameras for as long as I can get film for them.
