Personally, I'm a big fan. It's probably one of my most comfortable watches. I heat up quite easily and live in a fairly humid place so the rubber holds up nicely and is easy to wipe off at the end of the day. The deployant clasp is also top notch - feel secure, has a satisfying click and not too bulky. Rubber with the orange stitching certainly makes it more casual vs. bracelet or leather but I personally like the contrast and consistency with orange highlights. The color is also a little darker than it looks in the above picture and the "faux hatching" looks nicer in person IMO - make sure you check it out in person.
Not sure how it will age since I've only had it for < 1 month but I suspect the rubber might deteriorate over time and some of the stitching might fray.
