Of those listed, I use both Spontaneous (Core) and Unearthed Arcana Spell points with the vitalizing option (I also use Spontaneous Divine Magic (UA) and some third party systems).
As for the other systems mentioned, I dislike them and will not use them when I run. Furthermore, several of the listed options are, actually, deal breakers and I'll leave a game using them.
