Let's consider a concrete example.

[1]

template<class T> class greater_than
{
public:
    explicit greater_than(T const & v): v_(v) {}
    bool operator()(T const & w) const { return w > v_; }
private:
    T v_;
};

std::find_if(v.begin(), v.end(), greater_than<int>(5));

[2]

std::find_if(v.begin(), v.end(), boost::bind(std::greater<int>(), _1, 5));

[3]

std::find_if(v.begin(), v.end(), _1 > 5);

Which one do you prefer?
