In my opinion Convicts. They will spawn and spawn and spawn and they won't stop doing it until they are either old or dead. You start out with two and you'll have hundreds or maybe thousands within a year depending on the size of the momma.

Convicts on the other hand will defend their babies to the death and they even tolerate them in the same tank when they get bigger. They are very loyal and loving parents.
My FM pair had larger spawns then any of my convicts ever had. The FMs would also spawn every 3-4 weeks while they were in my planted tank. Once I moved them to another tank they would never spawn for me again.
