Can't say either one gets me excited.
With pedestal tables, you have either a hole in the floor or a bump sticking up, you have to find a place to store the pedestal when you lower the table, and they can get stuck. A 4-person dinette table requires 2 pedestals.
The only folding table legs I have personal experience with are Scamp's. While functional, they are fairly wobbly and the folded leg impinges on storage space under the lowered table. The hardware has some sharp edges as well, and I cut my head once while reaching for something at the back while the bed was set up.
Of the two, I'd stick with the folding leg because you don't have to manhandle the full weight
of the table when raising or lowering it. There might be better hardware out there if you go looking.
If I were designing my own trailer, I think I'd rather have a plastic, fully removable table that could be used outside. That's where we usually cook and eat.
A set of IKEA-style lightweight slats joined with cloth tape could substitute for the table to make up the bed while the table was removed.
