I like the Fizik Donna, and have it on all of my bikes. It is firm with good sit bone support, and a slight cutout. I am also very picky about my chamois, and I find that the thickly padded ones cause problems. As mentioned above, see if shops have a test ride program. The ones in my area all do, although they vary from shop to shop. One shop just allows 30 days to get a full refund. Another allows you to sign out saddles from the test set. If nothing else, a shop might let you set your bike up on their trainer, put a saddle on it, and ride the shop trainer to figure it out.
