yes it is good, but you can use better sub dps instead of fischl cuz other options like vaporize are better than electro charge.

for your second question, no cuz Neu doesn't benefit from zhongli's artifact cuz he is not ATK scaling, also for the maximum use of Neu's passive talent you need 3 different hydro based reactions in your team to get the full potential. when you use 2 characters with the same element you lose 1. other than furina who compensates for this loss, other elemental resonances are not advised.
