I like Kumquat a lot, they are a easy and fast snack.
On the contrary to most I like the normal small variety, exactly because it's more juicy.
I got a Meiwa, around 2 years ago and I didn't like it much because it was way too dry.
The first batch which came from the nursery was completely dry, like zero juice. The second batch was slightly better but I still prefer the juiciness of normal kumquat.
Plus mine was terribly full of seeds, like 2/3 of the fruit so not so enjoyable.
I have some giant kumquat which is similar to Meiwa( sweeter and dryer) but at least that has few seeds.
One of my favorites is the Orangequat variegated(which looks very similar to the centennial, not sure if they are same), very sweet and tasting like an orange.
The only drawback here is that peel is harder than normal kumquat, and although it's not unpleasant it ruin a little the enjoyment.
