Author here! CTC models perform quite well and are easy to get started for beginners with an added benefit of real-time streaming capabilities. RNNT's and Encoder-Decoder like Listen-attend-spell are also very solid choices, and literature points to slightly higher accuracy with them on academic datasets. RNNT's being and extension of CTC are streamable as well.
