For the longest time, i've been a big advocate for the HotBits. I went for a brief ride in 674/1000 and they felt pretty damn good. However i'm not entirely certain that a current production kit would be on the level with the Ohlins R&T, which i think are the model in question here?
I recently spoke with someone who has done some tuning and servicing on the HBs. I was kind of gushing over them, and explaining that they had been long regarded as the best, if not one of the best, GVR4 specific kits. Their experience was that while they are a fantastic product, they don't always come out of the box "perfect".
I think that we can be fairly certain that Ohlins are going to be about the best GVR4 specific kit that money can buy. I'd love to have some data comparing a HB DT1 kit to a R&T kit.
