The choice of bike you should go with depends entirely on your riding style and requirements. The Triumph Speed T4 is the more capable and quicker machine of the three. And, if you spend a lot of time at highway speeds or want to do reasonably sporty riding, it will be a better fit.
The Royal Enfield 350s are slow machines, but are soulful in a way few other bikes can emulate. If you enjoy a torque-rich, characterful, laidback and comfortable riding experience, the RE 350s are a great option. Take a test ride of both to see which one suits you best.
