Well, "Chacun son goût".
It just goes to show that everyone has his own taste. I have a Paradox, two O/U combination guns, and a drilling. For me it is the drilling that is the real "goof gun".
The combination guns (7X65Rx12ga and 9.3X74Rx12ga) have been fun for hunting. They are heavier than a double shotgun but easy to shoot and the rifle barrel is accurate. I have used them for deer and birds. Unfortunately, you only get one shot at birds or one shot at deer.
My drilling is a .30-30x16ga, lighter than some drillings but still heavier than a SxS shotgun or a bolt action rifle. I find it unbalanced toward the front and awkward to carry. It is nice to have two shotgun barrels but you still only have one rifle shot. The two triggers, safety, and barrel selectors are so goofy that I don't even bother to use this gun. Every time I've tried I found myself fiddling with the switches and triggers trying to figure them out. I'm sure I could train myself to get used to it over time but, for me, the operation of a gun should never be complicated.
The Paradox is a different matter. It is just as light as, and handles like, a good SxS shotgun. Either two rifle cartridges can be loaded, or two shotgun shells, or one of each. It is a double rifle AND a double shotgun AND a combination gun that can instantly change jobs just by dropping in different cartridges. No goofy controls - you can't get easier than one trigger per barrel. The removable sidelock action is simple and reliable, much more so than a drilling action. As a rifle, it shoots accurately as far as you would want to shoot a rifle without a scope. Shooting the Paradox with shotgun shells is just like shooting a SxS shotgun. It does just fine on a clays course with no weird patterning or strange behavior. If I handed you the Paradox and a couple of shotgun shells, you would shoot it and think it was a SxS shotgun. If I handed you the Paradox with two rifle cartridges and a rifle sight flipped up, you would shoot it and think you just shot a SxS 12 bore rifle. It truly has two personalties.
I just read that Holland & Holland is making these again in both Royal Sidelock and Round Body configurations. I guess that's the real answer to this thread regarding a "Modern Paradox".
Again, it's a matter of personal preference. I know what I like and you know what you like. We are lucky to have so many choices.
