I don't believe it's controversial. There are just many ways to do it. (There is no one right way to do it.) Even not doing it can be okay. My thinking is it depends on the phenotype and how the plant is growing.
I think with your plant, I might reduce the light to get some stretching (i.e., internodal spacing). I can't tell how tall it is, though. That would allow more light penetration.
A few more weeks of vegetation might help. It looks healthy, so it should continue to grow well. Let those tops develop.
I usually only top once, but sometimes I top the tops. (So, I suppose it would be three times.)
