I've grown all of those at one time or another, and they all have their good points. The closest you will get on floral effect to a cutting-grown type of those would be the multibloom. I've done them in years past as a floral potted crop and if grown correctly they're lovely. I'd say they tend to be like a floribunda......extremely numerous, but smaller flower heads.

That being said, I've also grown the bull's eye for a novelty. They've an extremely dark leaf along the lines of the black magic series and the pastel ones play off well against the dark foliage. They do sell that in a mix and that's also a benefit for somebody growing as few as you will be doing.

My standard seed-grown line for premium bedding flats would be Orbits. They can be close-cropped on the bench, are early and have a nice habit but were developed for mass production. They do well in the garden, too.

I sow my seed-growns I don't buy from plug in early December and do not pinch. I don't know your locality, but judging from the zone, I'd say a December sow is not giving you a lot of time if you are planning on a pinch, as it can add six weeks to a finished schedule in pots. A spray of cycocel (a type of growth regulator) will help to finish them off more quickly by a week or two. I don't use them anymore, but know when I was growing many thousands of them a year, I needed as rapid a bench turn over as possible.
