Most modern roses are better than Dark Night. It's one of the most disease-prone modern HTs I've seen since the 1990s.

Since 'Love' is the bicolor staple still being sold all over North America, that's probably the one to compare, then compare it to others similar in its era. At least from a commercial grower's POV.

The foliage is better. Love has a decent plant shape and decent bloom shape, but the color is drab, and the foliage is very matte red to green, which is not that attractive. Resistances are average, which is sadly better than, for example, Snowfire. Cherries and Champagne probably win in the vigor and foliage selection arena. But the color and form have a problem. They're not very defined in any way. If I was working at a premiere nursery, I'd still direct a non-rosarian customer to 'Love', because I know its a staple that delivers and I won't get in trouble for overselling a product.

Or to be honest, I would tell them to forget an large-flowered bloomer and just get Take It Easy, because I know that's the best current answer out in most nurseries.

So, this leads me back to your original question: I don't think that "it" bicolor HT has been produced in a very long time, and so I have to give a sufficient answer outside of the norm.
