Most stable, smooth, battery efficient Sense 7 ROM?

Over the time, my stock HTC One has become laggy and bettery life has been pretty bad. (I am on stock 5.0.2)
I, now, am looking to root my One and want a stable, butter smooth and battery efficient Sense 7 ROM. I came across many Sense 7 ROMs in development section - InsertCoin, ViperOne, SDv6, Artmod and others. Can someone suggest which one is the best in terms of the parameters I am looking for?

Thanks
