The fairy is better than the Hitachi cause it has more speeds. The same level of power on the top speed as the Hitachi. Plus it's less expensive.
I use my fairy wand for muscle massage as well and it's great! Amazing as a sex toy too, never fails.
The best body massager for non-sexual use on EF is the InfraRed heated massager
I have both. I now use my fairy as a toy, and the infrared as my body massager. It's the best general massager I've ever used by far! It's amazing. It does not really work as a sex toy though unless you use the single numbed pin pointed head attachment on your clit. Which I have and the heat feels good on that too.
There are tons of great attachments for it included that I think could work for a guy's sexual needs too.
I recommend you get both. If your mostly looking for a sex toy get the fairy. But if your ready for a serious therapeutic massager get the Infrared massager.
