TrueCrypt is the ONLY noncommercial alternative I'm aware of that's cross-platform.
Moreover, the TPM support (and secure boot on 8/8.1) features which make Bitlocker more convenient (although neither is mandatory) keep it from being as secure since it unlocks the volume automatically without a user unlock and can be vulnerable to some attacks on that basis.
The prior version of TrueCrypt, 7.1a was mature and stable for 2+ years without needing a point update. There were a couple of cases of law enforcement being unable to crack it (granted, this was in non-national-security casses).
Deniability is basically useless as the decision matrix always says to use it and thus whoever is trying to get the information will always assume it's in use.
