I guess it depends on your needs and wants. If you want to feel some internal stimulation, a rabbit is for you but if you just want clitoral stimulation, a clitoral vibe will work just fine.
The unfortunate thing about rabbit vibrators is that they're very anatomy-dependent. One rabbit that may work wonders for one person may be terrible for another if their bodies are different. I just ordered a VERY expensive rabbit-type/G-spot vibrator (the Zini Zook) and I'm hoping it works for me and I'm just going to cry and curl up in a ball and probably never get a luxury vibrator again. Lol.
