Ella should work for most people and the packaging is beautiful. The silicone is top quality. It's small enough to work for a beginner.
Figi looks interesting. I don't have it, so I can't say for sure.
I have No. 8 on order. It and the Wave Wand look similar to the Swell Wand which is one of my favorites! The No. 8 is pretty slim and should work well for someone new to toys.
I have the Bent Graduate and I think it's just okay. I was expecting the world of it, I guess, and it didn't give me the amazing G spot orgasm I was hoping for. I assume this is because my G spot is picky though. I would go with Ella over Bent Graduate because Ella has the flat head and I think that tends to work for more people. I haven't taken a poll or anything on the topic. That was, I believe, why the Bent Graduate didn't work as well for me. My G spot didn't like the pointy head so much.
Amethyst is similar to Bent Graduate, so see my comments on Bent for comments on Amethyst.
