Excalibur Red and Deng Suria (also known as Red Morning) are a darker more pronounced red. Cristela is lighter red with a tinge of pink.
Rob,
Do you like Cristela? Mine is a few years away from producing. It should be noted that it is not a vigorous grower.
The tree, that is. Not the employee. 
You see, now I was going to replay that we are just friends.

Yes, the Cristela jackfruit is very good. Not the best, IMO, but very good. If picked and ripened properly I feel many jackfruit are very good to excellent, some moreso than others but sometimes its splitting hairs. Now I will also be honest that some, while not bad, I don't feel are at the same quality level as others but this may more of a personal/subjective thing.
