There's no rights and wrongs here, each V1 within the range is good enough and satisfying performance requirements.
However, choosing lower V1 will improve your stopping performance, so perhaps it's advisable if the runway is wet/slippery, or the stop margin is low. Some people say it is better to be 'go minded' and use lower V1, to enable them to continue the t/o rather than stop in case of engine out.
Higher V1 OTOH will enable you to stop until higher speed, but with a lower stop margin. Also, you will probably use less runway for continued takeoff, have better screen height, perhaps attain higher speed for climb (even though V2 is fixed) and better climb performance. Could be a good idea if obstacle, or climb gradient are the limiting factors.
Anyhow, it is up to the Captain's judgement, there's no black and white here
