I prefer my high end inverter for a few reasons. Don nailed the first one, it has a fast charger... 125 amp capacity, so it replaces my AC/DC converter for the rare times I'm on shore power, and makes the most of generator time when I'm docking.
Secondly, I like the integration. Charger + Inverter + ATS all in one compact box. It's wired "whole house" so my entire RV is powered through the inverter. Shore power cord goes in the input, existing circuit panel wired to the output, easy peasy.
My only regret on my system is not spending the extra $1000 to buy the 48 volt model. The 12 volt version is working fine, with its massive cables, but it's lame duck technology. It's never (from my engineering opinion) going to adapt to a lithium battery technology, where the 48v is better suited.
Look long and hard at going with a higher voltage system. It makes a lot of things easier. Solar is easier at high voltage, inverting is easier, cabling is easier, the only hiccup is a 48v to 12v DC-DC converter to run lights and appliances, and that's not really a big deal.
