What is this cherry?

[NewWestGardener]

I have these big cherries that i have no idea what they might be. At first I thought they are Sungold, but they are much much bigger. See the picture, the regular Sungold F1 is on the right. Due to lack of water, all 4 of my Sungold are small this year, but not these. Some cracked now due to recent rain.
All Sungolds are F1 seeds . They might have come from Canadian seed exchange from Nicky, marked as F1, I did not plant other orange tomatoes this year except for Jaune flammee.
They look and taste like Sungold, tall plants. Could it be just another Sungold?
What's everybody's best guess?
I'll save some seeds regardless.
