It depends on your price range. There are still pretty strong clit vibes for good prices.

One of my favorites is Tango by We-vibe. MiMi is like "the vibe" here. However, Eden has pretty good search features and you can type in your specs and see what comes up. The reviews will guide you as well.

Hope that helps!

It depends on what you like on terms of texture, noise, etc.

I haven't particularly tried many vibes, but the crystal high intensity bullet is pretty awesome, especially for the price.

It depends on your personal preference. You've just said that you want something strong. That doesn't factor in noise, shape, size, what type of vibrations (rumbly versus buzzy), pinpoint or not, what your price range is, what your basis for comparison is...
