I apologize if this has been touched on within the thread because I read through but didn't see it, but I feel it's pertinent to note that grafted roses are often sold as bare root and they are not different unless potted.
OWN root roses, which seems to be the actual query here from what I've gathered from so many wonderful responses, may also be sold BARE root.
I only wish to avoid confusion on the matter.
For Own Root or Grafted/budded, I do find that in my cold climate Z5b that roses on Dr. Huey generally aren't as impressive in the longer haul versus own-roots. Of course, there are so many variables involved.
I have Lady Emma Hamilton grafted bare root from DA I believe spring of 2014 then the oopsie The Ingenious Mr. Fairchild 2015, and was one of my firsts when I finally found the chance to get back into gardening in my adult life. I also have Winchester Cathedral from DA that year as an own root bare root rose.
LEH seems to be piddling out as of this summer and I have ordered a replacement from DA. I know it will be full of RMV just like my current one is.
WC I've moved three (?) times since I've gotten it, and it is just now starting to put on good canes and I expect more size 2021.
TIMF actually seems to want to put on size and was only suffered bad winter die-back 2026-2017 but even grafted to Dr. Huey, he seems to want to grow which I admire. It takes soooo long for him to grow thick canes. The juvenile ones are so thin and willowy. Plomph! Blooms right in the dirt.
I have Charlotte own root and where it's at, it isn't cared for but my mother says it's always blooming! It usually gets four feet high every year.
