Recoil isn't an issue for me, I'm big, experienced, have good form and 9 lb 00 shooters with long forcing cones. So, the regular 00 doesn't bother me.
The Estate SWAT Ammo(Some of which I can see right now) patterned tighter than any other. Less kick, but I'm not sure how much.
Prior to the Estate 00, the best 00 I had tried in my HD 870 was the Winchester standard stuff, which had been my old duty load,tho Federal wasn't too far behind.
If memory serves, the Winchester stuff runs 20-24" at 25 yards from my chokeless HD tool, and the Estate stuff 16-20".Your results may differ, but the various BB members who reported using this stuff were not mentioning ANY problems or shortcomings, TTBOMK.
IMO, the Estate SWAT 00 ammo is the best buy out there. Best performance, lowest cost...
