What's the Difference?
Two pink roses: what's the difference? That's 'Bishop's Castle' (Austin, 2007) on the left, and 'Mrs. B. R. Cant' (Cant & Sons, 1901) on the right.
They're both roses, both quite fragrant, both pink. One is a new(ish) David Austin rose, which you buy because you see a drop-dead gorgeous photo in the drop-dead gorgeous David Austin catalog, and think, "I want that!". The other is a rose from over 100 years ago, which someone gives you a snippet of for free, saying, "This will root if you stick it in the ground."
Do you spend a fair amount of money (plus shipping! and tax! and in this state, tax on the shipping!) for 'Bishop's Castle', because a gorgeous glossy photo has affected your judgement on the virtues of thriftiness? Or do you take the free snippet of 'Mrs. B. R.', and spend 4 years patiently nurturing it until it is big and strong enough to produce those gorgeous flowers?
Which one does the true rosarian choose?
Easy. Both of them.
