White Eggplants - you might want to consider one of the egg shaped varieties. Some people say there is a taste difference - white eggplants being a bit milder and fruitier - personally I don't discriminate based on color and don't really see much of a difference in taste - so once you go black - sure you'll go back [and forth]. In the eggplant realm the whites are the minority, but a novel deviation.
The absolute best of the full sized White Eggplants in my opinion is Casper Eggplant. It's taste is undeniably different, not just a subtle difference but a scrumptious variation. If you've ever read anything about these eggplants, you'll see them being described as tasting like mushrooms, and that is perhaps the best way to describe them. They actually do taste like Mushrooms - certainly don't taste like chicken.
Cloud 9 Eggplant is a prolific hybrid white eggplant. The fruits are between 5 and 8" long. Cloud 9 produces more prolifically and is easier to maintain than Casper, but the taste is not as good. It's still a good eggplant comparable in taste to most standard varieties.
Ghost Buster Eggplant is a hybrid White Eggplant very similar to Casper. They grow 6-8 inches in length and are fat and oval. It is very thick skinned and the skin should be removed before cooking. It is sweeter than purple and black varieties but can't compare to Casper in this department.
Gretel is another popular white variety. It produces clusters of glossy white Eggplants that are harvested at 3-4" in length.
A few other white varieties include "Blanche aubergine", also known as Albino, "White Beauty," and "Tango"
Easter Egg eggplants can be considered a white variety, but they also produce multi-colored egg shaped fruits and are listed further down on this page under Exotic varieties.
Increasing in popularity are the Asian varieties that hail from China, India, Japan, and the Pacific region. Asian cuisines use of eggplant differs substantially from western cooks and their produce reflects that.
One of my favorite Asian varieties is Ping Tung Eggplant from Taiwan. The Fruits are long and purplish, about 2” in diameter and up to a foot and half long. It is more tender and a tad sweeter than most eggplants.
Thai Kermit Eggplant is small green and globe shaped. It is harder than most other eggplants.
Thai Yellow Eggplant is a miniature eggplant variety, an Asian Heirloom popular in South East Asian cuisines. If you're a fan of Oriental cuisine in particular stir fry dishes - you'll like Thai Yellow eggplant.
Apple Green Eggplant, as the name implies, is green like a granny smith apple. It is a reliable and rapidly maturing variety. An added plus is that it is fairly easy to grow although not as disease resistant as some hybrids.
Red Ruffled Eggplant also known as Hmong Red eggplant is my favorite red eggplant. It looks like the byproduct of a Ménage à trois between a tomato, pepper and eggplant - if that were at all possible.
Easter Egg Plant is grown both for ornamental purposes, as well as edible, it produces an abundance of multi colored Easter egg like eggplants that are not only tasty but picturesque.

Striped Toga Eggplant are borne in small clusters on a 3 - 4 foot bushy perennial plant. They start out yellow and gradually morph to Orange with green stripes. Grown largely as an ornamental they are also as edible as any other eggplant is.
