Be still my beating heart-lavender/mauve/violet/"purple" roses are my sweet spot. Purple Skyliner is an absolute favourite. RdViolettes is maybe THE most beautiful rose in the world,IMO. I pine for Quicksilver ,Aunt Margy's, Lavender Crush...none of which are available here in Europe. I'll have to look up the others you mention...
Now, let me explain: I put "purple" in quotes because you've gotta be careful-many times a rose is described as purple, when in reality it's just a banal reddish colour. Purple Skyliner is adorable-I hunt around in my mind for critiques I could make of this rose ,and there are some,but in my garden, my situation, the conditions are extremely tough,and this rose does very well even for me. It's quite vigorous,and does establish even in a difficult condition if given time,and doesn't demand much attention. It does have to be supported in order to encourage it to climb,at least for me.It would probably do even better in a "normal" garden.
RdV is stupendous, but does need good soil and nutrition; I have not yet succeeded in growing this rose really well, but the flowers are so breath-taking , and I am working on it. Again, I want to remind you, I have extremely tough conditions. For pure beauty of the individual flowers, I'd vote RdV. For the cascade of flowers that fall down like the long hair of Melisande or Rapunzel,Purple Skyliner is the one.
