My 200 had the Linc system and when I was shopping I originally was looking for the analog gauges due to concerns over the long term reliability of the glass display. But most 200s have the Linc system and that's what I ended up getting. There is one big advantage to the Linc system over the gauges. It'll read and display engine DTC codes. Which is supper valuable if you do your own engine work. With the analog gauge set you have to buy the $700 Diacom software if you want to be able to read engine codes.
In the end, both the Linc display or the analog gauge set on a boat may fail over time. Predicting which one a company like Nautique, or any other one for that mater, will still have in stock as a replacement part is kinda a gamble. And it may be an invalid assumption that replacing the analog gauge pack is any cheaper than replacing the Linc unit. Since more 200s ship with the Linc system, it possible that it could be available as a replacement part longer than the analog gauge set which I think is also one integrated unit and not individual gauges like days of old.
I don't get the point people are making over upgrading software. There is no real reason you'd have to upgrade software on any of these glass displays. Maybe there is a tweak or new feature that would be nice, but it's not something you have to have. In the case of ZO integrated system on newer boats. I'm pretty sure it's just the display and control of ZO handled by the glass display. I think there is still an independent ZO computer module under the covers and software on that is what would be upgraded for a new version of ZO software, not the glass display. But that is something I'd want to verify before I bought a boat with integrated ZO. And in any case, supporting software updates on multiple versions of glass displays isn't actually a very hard problem.
The one thing that made me feel better about my year 200, is the engine starting and zero off where independent of the Linc system. So if the Linc did fail, it would just be like the analog gauge set failing. The boat would still work, I just wouldn't be able to see dashboard readings until I got it fixed. But that is becoming less true on newer boats and is the main reason I'm not a big fan of integrating the zero off controls into the glass display.
