The G4 Tiger from the ones you listed only mine is in the Red. Although I much prefer the G3 Semi Realistic as that thing's ridges just made me swoon thinking about them.
I love Fun Factory products because of the silicone shaft (not silicone covered plastic like some of the other name brands out there), the vibrations are deep and thumpy and not buzzy. And my G4 Tiger is one of my go-to toys.
I've also the Big Boss and he is a fantastic toy, but he is not a toy I use frequently because of his girth. He's great don't get me wrong... just a little on the yummy side of girth which is not always what I want!!!
In my next order I plan on having one of the clit toys; Fou, Yoo or UFO. Haven't decided yet!
