I have grown Grandma's Blessing for many years. I would say she is my favorite shrub rose! Until the blooms are fully open they look like a hybrid tea! She is very low maintenance for me compared to a hybrid tea. I grow her in a spot of poor soil, mainly clay and not even a lot of water and yet she does great. O special note, mine does not stay short, she get 5-6 foot tall every year. A friend in the Idaho Rose Society grows it and hers is also 5-6 foot tall. The only way I can see it staying short is if she were severely pruned. Also of note she own roots quite easily.
I prefer Yellow Submarine way better. Yeah, its a little lighter, but the bloom production and repeat is insane, its always healthy, and the petals drop. True Friendship tends to have forever petals, and the stems tend to bend into the ground. Also, Yellow Submarine is an insane honey bee attractant.
