Personally, I believe that someone must be buying those round steaks & chuck steaks. Go ahead and grab the A1 for them.
Personally, I'd rather eat PB&J sandwiches on steak night for 2 weeks, and enjoy a really good steak the 3rd week, than have a dry, tough, chewy steak with A1 every week. That said though, a slightly dry, tough, chewy steak with A1 isn't really that bad.
However, as far as "just salt & pepper" - I've discovered a couple of marinades at my local butcher that are outstanding. He's got some sort of vacuum machine that tumbles the steaks in the marinade for a while, helping to tenderize them & add incredible flavor to them at the same time. Darn it, I can't remember the names... black something or other, and some sort of bourbon based marinade. Cheaper cut of beef, but quite lean, and with the marinade (plus better quality from the butcher in the first place) just as tender as rib-eyes from a grocery store. It runs around $5.49 a pound vs. $10 per pound for decent rib-eyes. I almost prefer them over rib-eyes now.
