Dick's training might have been formal, but years of fighting criminals would have taught him to incorporate any useful street brawling techniques. I'd say Dick last time we saw him was pretty close to his peak ability, and he'd take Terry from the series down easy. If we jump to the timeframe of Epilogue, Terry has much more expirience and training, and I'm betting that's a much more even match. I'd still go with Dick though. Lifelong training is a huge advantage, and he was trained to work a trapeze from the time he could hold on to one, then learned many different fighting styles.
Also, formal training isn't always so rigid, especially when you begin learning multiple styles and mixing them for the best results. Being adaptable to any situation was a key point of Bruce Lee's philosophy when it came not only to fighting but to anything in life. and he is probably one of the greatest fighters the world has ever seen.
