I keep nine separate species aside from my two splendens.
I fell into the trap of purchasing a lot of splendens because I really only liked their colour and nothing else. Then when their colour changed (because I only purchase marbles) I had all these fish I had to dedicate time, money and space to that I didn't really like all that much.
It's why now I usually only get wild bettas since their appearance doesn't drastically alter, I enjoy having them around, don't mind dedicating time and effort to their care, and if they do spawn for me this is an added bonus.
Only time I would get a splendens now is if it has exemplary form and a nice colour. Otherwise I won't bother. Costs too much to have tanks running that are filled with fish I don't particularly care for. I shaved a couple of hundred dollars off our power bill simply by closing down half the tanks I was needlessly running.
