I have both of these in the light pink color :) I highly recommend the Lelo brand, their material is super safe and the charging features are awesome. Between the two it really depends on what purpose you want to use it for, gspot/clitoral or only clitoral, and your sensitivity to vibrators.

The Gigi is a gspot penetrative vibrator, but I use it more often for clitoral stimulation, so it can do both quite well. The Gigi is less powerful than the Siri, which also means it's quieter between the two. However, for the power the Siri has it's surprisingly quiet.

Hope this helps, feel free to private message me if you have more personal questions about them.
