There is no way to no for sure if they have the same type leaf until they produce some fruit. Then you will know.

But in general cherry tomato plants grow faster than non-cherry types so IF they are about the same age the taller one is most likely the cherry.

ok thank you

Well, you _might_ be able to tell the difference between which are cherries and which are not cherries... So maybe you might be able to pick out the big boy from the rest.

The cherries I grow generally have smaller and firmer foliage. Even without tags, I can pick them out. Of the seedlings I grow, cherries and paste types are the most easily singled out of the mix; Cherries are as described above and pastes (the ones I grow) are very flimsy looking.

You'll definitely know at the time of flowering though, cherry flowers are significantly smaller and often more numerous.

Easy to tell ,wait a few weeks

I would think the flowers for the cherry tomato would be in clusters of 6+ while the big boy would only have maybe 2 flowers per cluster.

basically the cherries will LOTS of flowers while the big boy significantly less.
