I don't have a real comparison to other DBM models or forged irons other than more maltbys, but my TS4 are like butter or like I hit nothing on flushed shots. They provide much more feedback than my previous GI irons on mishits. Compared to my buddies regular TS4s they do sound a touch more clicky, but I also have no noticeable bag chatter where his are showing a touch of wear.
I love my TS4 DBMs so damn much, but your mileage may vary.
