The answer to that question often turns on the vintage. In the better vintages, say like 2014, I may buy all of the cuvees from some of these producers, where in lesser years, perhaps only what I consider to be their flagship. So, it depends.
Generally:
On Roilette, I usually only buy the Cuvee Tardive over the normale as the up-charge is minimal and the quality difference can be significant. I buy the Griffe du Marquis in most years.
I buy the base Thivin CdB in every single year. The U.S. has only recently been carrying some of the SVD cuvees, and I generally try to grab them in quality years. They are good, but often much more expensive than the base CdB, and not always worth that up-charge. This is one of my favorite buys in most years.
Lapierre, the San Soufre every year, it’s exceptional. The Lapierre Lapierre is often to large-scaled for me.
Bouland slays it across the board in quality years. I generally buy across the board, with the Delys Cuvee being the flagship. I found the 2018 Delys a bit OTT.
Foillard makes one of the greatest Beaujolais in the marketplace, the 3.14. Can be stunning stuff.
I like the Metras normale, really lovely stuff, but it and all of the upper-cuvees have gotten quite pricey. The flagship cuvee, Ultime, can also be stunning. The 2014 is a jaw-dropper.
This list has wines in the sub-$30 range (most sub-$40), which is amazing given the quality, up to wines above $75, the 3.14 and l’Ultime, which are world-class wines by my definition. I just bought some 2017 Roilette Cuvee Tardive for $23, which is just a stupid price for what is already one of my top 5 QPRs in the world of wine, normally it is around $28.
