Only you can know whether it's worth it. Straps are a consumable item and I, for one, am reluctant to spend >£50 on a strap. The difference between a nice embossed (ie Hirsch) and the genuine article is usually obvious side by side, though not always. If it's a black strap, I'll wager you wouldn't be able to tell. A Hirsch embossed (ie Duke or Grand Duke) are well made, look good and do the job. In my experience real croc/gator doesn't last any longer than embossed calf.
