I don't know what the DS means. is it part of the number or separated some. If it is separated it could be a lot code. Here is a data sheet.

Is there any reason to think they are different, other than that number? Do they do the same job in the circuit? Usually the letters on the end refer to packaging.

In general the TL074Cxxx parts are commodity items and very interchangeable among manufacturers. The alphabet soup after "TL074C" varies from one manufacturer to another and is a code for things like the physical package (DIP, SMT, etc), the vendor "put-up" (loose parts, plastic tubes, tape-and-reel), special lead forming for automatic insertion, the die fab location, the packaging location, manufacturing lot code, etc, etc.
Somebody may have discovered, by accident, that parts from a particular manufacturer . . . or a particular fab . . . or a particular production lot . . . are superior in some electrical characteristic such as noise, offset, bandwidth, etc, but that information is seldom very easy to find.
