I'd put them in order of 1 Room and Board - Significantly better then the rest in terms of quality. One the best values in the market. Solid mid tier furniture. It will last for several years Ok quality, but this is really lower mid tier2 Crate and Barrel3 West Elm4 Article - Similar but slightly lower quality then the others 5 Wayfair - in some cases worse then IKEA... basically the same quality as amazon. Thuma - No experience. If you want mid century modern, the look at DWR as well. It can be pricy, but it is authentic. R+B is similar in that they also re-sell some authentic MCM pieces. Also check out Hay, Blu Dot, Mash, Ethinicraft, and of course all the OGs like Herman Miller, Vitra, Steelcase etc. More on reddit.com

In general, I would avoid any furniture from West Elm, should your search take you in that direction. I have been fooled twice, buying what appears to be quality furniture, paying a lot of money, and being left disappointed. In short, they sell overpriced, cheaply-made furniture. More on reddit.com

Sweetmodern.com buys old pieces and then restores them for you once you buy them. They constantly acquire new mid-century furniture. I’ve bought a few pieces which will be delivered Memorial Day weekend. More on reddit.com

best best: facebook marketplace. here's how to get first dibs, though it takes a lot of luck and time on the website. "season" or optimize your FB marketplace algorithm to find MCM furniture - you can start by typing "mid century" into the marketplace search, and maybe in a wider area (40+ miles). click on a bunch of posts to make the algorithm recognize what youre looking for - you'll inevitably come across resellers, but every once in a while you'll find a great deal on an item that isn't marked as MCM, but that the algorithm has recognized as mid century. for example, today a drexel declaration bookshelf was listed for $40(!) - i didnt get it, but the algorithm brought the item forward as the first listing. hope this helps in your search More on reddit.com
