Stock for stock, New Edge is much more livable on a daily basis. Once you start to get in to modded stuff the waters get plenty murky plenty fast. A well sorted Fox will run rings around a stock New Edge and vice versa. Similarly modded they will run similar times since the under pinnings are basically the same with changes in where the cars make power.
Best bet is find a club member and ask for some ride alongs. You will find the answer comes down to personal preference. FWIW you couldn't pay me to live with a fox interior on a daily basis, wager you will have a lot on the otherside of the same arguement.
