I'm in zone 9 and I prefer hybrid teas, floribundas, and modern shrub roses. I've never grown species roses on purpose, although a few have sprung up here and there. Most OGRs leave me cold, except for a few gallicas and tea roses. The bourbons and noisettes are the worst culprits as far as vunerability to pests and diseases is concerned. I've lost my affection for most of the Buck roses because they get too much black spot in my garden. Polyanthas are easy to grow and to keep happy, but their blooms don't usually thrill me. Hybrid perpetuals are pretty, but they have virtually no disease resistance in my garden.
