How much gain do you need? In most cases the answer is none.

However, if you want gain then I guess an Aikido is better then SRPP. SRPP is fine for driving a little power into a known impedance (such as a headphone amp) but can generate distortion for the 'wrong' load impedance. Unless, of course, you like distortion (some do!).
