I own 3 different species - tomato, GSM and false perc.
For absolute beauty the GSM wins, hands down. Not exactly my most friendly clown however.
The false perc is the friendliest, as well as my goofiest swimmer.
The tomato is my oldest clown. I got her in 1993 and she is doing great. She stands up to the 2 damsels that broke in my first SW tank. (I know, we don't cycle a tank with damsels now, but that was the way it was done in 1990.)
Lynn, I haven't directly answered your question. I love all of my clowns, but all for different reasons.
