Shailesh,

WPA and WPA2 are both 100% vulnerable to brute force attacks, take a look at cowpatty.  It's supposed to take a very 
long time.  It's extremely possible to brute force WPA/2, google it.

If Security is the criteria, then I would suggest you should be using WPA2 rather than WEP.

WEP with the now infamous RC4 Stream Cipher is/ was a security nightmare.

WPA2 uses AES Block Cipher with a 256 Bit Key and currently their aren't any known compromising attacks against it.
As regards to the cipher, AES remains secure & unconquered while the 256 Bit Key is completely immune to any brute 
force attack(s).

You may also wanna check NIST SP 800-48 that deals specifically with Wireless Security.
