Wave's Rise is much better. That's this one

She's been out for a while, but she got a rerelease, so she's still pretty affordable. She's only about 5,000 yen opened, like here

The newer Megahouse Rise based on P4A is a disappointment. Like Yukiko, they're just doing an awful job with the Persona line. I have Chie preordered, but that'll probably be the last one I buy. Since she was an exclusive she's a lot more expensive, about 10,000 yen on mandarake. Definitely not worth it compared to the much better Wave version.
The Lisa Silverman figure is pretty good. She didn't blow me away, but I don't regret getting her either. She didn't sell very well so you can actually grab her pretty cheaply, about $41.60 shipped to the US.
