Both titles have been getting better. Batgirl was always see-saw for me. Sometimes good, sometimes not, but lately... say the last 4+ issues, have been very enjoyable. To be fair, 1-2 of those were a different "fill in" writer. But I think it's going someplace interesting.
BoP has very hard swings. I actually liked what they had going early on; I liked Katana on the team over Strix, but that's more from the limitations of a mute character. They've been building the series back up and I actually like Christy Marx as a writer.
If you are someone who buys the trades I don't know how I'd recommend it to you.
