So there are some that swear by it and others (me)
that swear at it.

I alternate between the two! I used to keep all Phals in spag, but no more.
Now I use it for small Phals which need to grow their roots-keikis and
plants that have had trouble. For me, it's fine in a basket, but not in a
plastic pot. I also use it in certain mixes. For my mature Phals, though,
most are in Aliflor and get watered twice weekly.

There will always be a place for spaghnum, however.
