I think the Coach 1941 bags are comparable in quality to higher end designer bags. Some of the regular Coach New York bags, if I am being honest, are also up there in terms of quality of stitching and structure.
My YSL College Monogram Large had a cloth interior and was, at the end of it all, a top flap bag with a cheap faux gold finish chain. The packaging from the store that shipped it to me was very basic, the ordering service was basic as to be almost subpar, and it came with NO note, receipt, or additional ribbons or boxes. The return period at the time was also 7 days.
When I bought my Coach 1941 rogue, I received ribbons, a box and a dustbag that fit the bag well. The receipt, as all Coach orders do, came in a branded envelope in heavy cardstock in matte black. It felt like a gift to myself and I hadn't even ordered gift wrapping service.
Louis Vuitton orders in store and online have similar presentation, sans boxes for bags, though.
Gucci takes great care with its SLGs in store, similar to Coach 1941 and Louis Vuitton, but I cannot say anything about the bags aside from the quality I perceived of them when in store. Most current Gucci bags have fabric linings.
The hardware does not feel anymore luxurious in premier design houses like Gucci, YSL or LV, etc. It's all the same. I take that back some of the Coach 1941 hardware, especially at the outset of the line, seemed more substantial (perhaps even heavier).
I am in the minority in that I dislike leather linings because of weight, but if that's the standard, Coach meets and exceeds. I think some of the personal feelings around Coach being high quality are regarding the fact that they design in the USA and produce 1941 in Vietnam and not in the EU (but tthat's certainly another topic).
