Hormonal tits always look natural whereas pumped up tits often do not, because they are either badly done or overdone. Most tgirls are naturally small-chested & should chase more modest results with their implants.
That said, some pumped up tits do look more realistic than others. This could be due to the type of implant, the tits becoming more natural-looking with time or the girl is bigger to start with.
Hormonals - always look good.

Pumped up - depends.
