Is this two names for the same tomato or are they different?

They are different. Google is showing a lot of them mislabeled I believe.

Pineapple is a bicolor red and yellow tomato and Hawaiian Pineapple is yellow. I grew Hawaiian Pineapple once on accident because it was just labeled Pineapple. My dad grows Pineapple every year and it is his favorite.

How does the flavor and production compare between the two? I am growing both this year and have a few of each so far on the plants. I have tried one Pineapple and it was good. That said I am having a very bad year overall. Based on the one Pineapple I am going to save seeds and grow it again next year and hope we have a better tomato year. Everybody I know around here is having a bad year.

I remember the Hawaiian Pineapple as being mild and sweet, with a nice smooth texture. The Hawaiian Pineapple did not produce a lot of tomatoes, but the ones I got were quite large with some slight green shouldering. Me and my wife enjoyed them in sandwiches (we put them inside grilled cheese).

It has been a lot longer since I had regular pineapple tomatoes but I remember thinking they were delicious too. I think they had a more complex flavor than the Hawaiian. I think the regular pineapple was more productive as well, with neither being prolific.
