It all depends on the type of flying you want to do.
If you want a comfortable aircraft strictly as transportation to fly your family to your destination, with the ability to cruise in pressurized comfort up high above the clouds, then the Meridian may be for you. The Meridian has a very nice cabin for passengers but you can't put much in it due to lack of payload. The cockpit is very cramped and hard to enter/exit between the seats, and the limited cockpit view outside IMHO is like looking out the slits of a bunker. It also has only a single piston engine (stressed to provide pressurization), so I'd be concerned about flying it over inhospitable terrain.
On the other hand, if you really like to fly, and want to view the scenery passing below with fuel consumption low enough to fly around on nice days without always having a specific destination in mind, then the DA62 is for you. You're already familiar with how it flies since the DA62 handling is virtually identical to your DA42NG. But with slightly better performance, and far more interior space.
To me, the DA62 is the ideal of a fun-to-fly recreational airplane combined with a serious traveling machine you can fly at night, over mountains, big water, etc.
