My 'Albertine' is the healthiest rose of the three you listed.
followed by 'Buff Beauty' which shows a fair amount of blackspot afer October, which may not be a problem where you live as the bloom season is shorter further north. I rate my plant of 'Celine Forestier' and Perle d'Or' as being on my "A" list for disease resistance, and Buff Beauty as B+, for comparison of yellow roses.
Luanne, my neighbor got rid of M.I.P. and I shovel pruned the pink sport of it, M.Ernst Calvat,in my no-spray garden. I miss its' intense fragrance but they both were ridden and riddled with every rose foliage disease, blanketed with powdery mildew during our cool and moist springs, blemished with mildew which I rarely see on roses here, speckled heavily with blackspot during our warmer autumns, and rust in August. I even sprayed it with Cornell in my former garden but it was not worth the effort. We both now grow Grandmothers Hat which is very healthy, here.
We both grow 'Souvenir du Dr. Jamain' in our no spray gardens and it's among 5 of the healthiest red roses in our gardens among 200+ rose cultivars and species. It is considerably more disease resistant than 'William Shakespeare 2000' grown in the same garden which gets blackspot to a moderate degree here.
It is now December and the foliage is nearly spotless on Souvenir du Dr. Jamain'.
W.E. Lippiat' is a gorgeous crimson H.T. that is even more fragrant, and nearly as healthy as s.du Dr. J..
I hope this is of some help.

I have never grown a rose more susceptible to disease here than MIP. Yes, it even blackspotted. The blooms were lovely -- it was in its time my "go-to" rose for English Box entries (and Kim will remind us that it is exactly this sort of rose for which that class of competition was invented) but that was the ONLY way I could show it.

Aside from that, it had scant virtue here, having very stiff canes, with horrible prickles.

Mme. Ernst Calvat was, here, just SLIGHTLY more disease-resistant than her sport parent. I AM glad I grew her, for in the time she was here, some blooms sported wholly or partially back to MIP -- confirming for me the theory that she is a sport, and not a seedling, of MIP.

Regular spraying never helped either of them one bit. And I can't even say their foliage problems were due to our longer growing season, because both rushed into mildew and rust early in the year, which to me is unforgivable.

One oddity, the flowers are very fragrant while on the bush, but lose all fragrance when cut.

Years ago, when we were active exhibitors, we entered a REALLY lovely spray of BB at a Fall rose show.

It didn't win the Shrub class, but several people approached us after judging to ask for information on that interesting new Austin . . .
