I bought the Topeak DXG specifically for bikepacking, but also because it was time to update my circa 2001 shock pump. I didn’t do a rigorous comparison with other available shock pumps with similar features. I did partially select a piece of Topeak equipment based on being impressed with other equipment of theirs that I have. Bottom line is it works great and does the job it’s supposed to do. The quality and overall finish are top notch as well. The connector is a major delight, especially over my old shock pump, in that it really does eliminate pressure loss when you disconnect. No more over pressurizing and hoping you’ve guessed right for the disconnect loss. I thought about getting their lighter version with no gauge, but my experience with both front and rear air shocks is that, at least for me, there really is just a very small range of optimal pressure to get the feel or performance I want. Since I know what my “unloaded” shock pressures should be, for a trip I need to add to that, which is usually some trial and error on the trail the first day. I was afraid that with no gauge, there’d be a whole lot more trial and error getting the right pressure. Nice compact folding design, easy to read gauge, and a pressure release valve round out the features, which all in all I’d give it a 5 for a rating.
