Not ruffle anyone's feathers but, some of the comments here sound like an argument of Ford versus Chevy having some farkle the other doesn't and getting upset over the whole issue.
I have done more than picking one up from a rack at a gun show. I have 'skin' in the game.
I currently own the following double rifles: 1 Heym, 1 Verney-Carron, and two Chapuis.
The two Chapuis are fine rifles but, I also bought them when I didn't know much about double rifles and was looking for a "bargain". There is nothing functionally wrong with either rifle but, they are also my two least favored doubles.
The V-C and Heym to me are pretty equal but, really different rifles. The Heym I have is a no-nonsense working rifle and looks a little plain. The V-C is the supermodel you see on the cover of Sports Illustrated or the Ferrari that just set the new auction record. Both rifles handle like an extension of my body and are effortless to mount and swing on a target.
The Chapuis rifles to me in comparison are 'clubby' and not as attractive. They both feel slow to mount and seem more awkward to swing on to the target. While not 'homely', they are not supermodel pretty either. Chapuis, at least when I bought them, didn't really offer options and it was basically a take it or leave it proposition.
Verney-Carron custom builds so, you can get whatever you are willing to pay for. Heym really doesn't offer much in the way of options beyond wood but, in a no-nonsense working rifle nothing is missing so you don't have to 'option up'.
If you want a lot of flair and eye candy, V-C is still where I would go. For a hard-working rifle that will see a hard life in the bush, I'd happily get another Heym.
In all honesty though, today I'm keeping an eye out for an early 19th century British double though, a classic British bolt action might find its way to me as well if it is a 404 Jeffery.
