Pygymies are heap cuter but I am totally biased
The reason I chose to keep and breed pygmies over centrals was really driven by their space and food requirements. I also didnt want to just follow the crowd. You can feed 3 pygmy beardies for the same amount it takes to feed a central and of course they will comfortably live and breed in a 3 ft tank. I wouldnt dream of putting an adult central in such a small enclosure.
Granted that pygmies dont come in the range of colours that centrals do, but that is just a matter of time. Given that they breed at 10 months old (when fed enough) it wont take long to get through a few generations and add some colour.
In the end if you cant decide just get both
