If flooding is your biggest concern, there aren't really many choices out there for you besides the Eve. The poor resale value is caused by Ford's propensity for having sales... and the perception was boosted by the fire sale Ford had on the old pre-TDCi units when they were about to introduce the new ones... where they sold them for under 1m (previously, they were selling for 1.2 - 1.3). That was the big trigger. For the newer one, resale value isn't the best there is, but it's not horrible. IMHO, it shouldn't be a consideration unless you plan to replace the vehicle in just three years... but if you're buying an SUV, you should be looking at long-term ownership... because even Fortuners lose about 500,000 pesos in value over two to three years. And that hurts. Still... passenger comfort is a weak point for the Everest. If you get the variant with the normal wheels (not the 18s), it's better, but it's still quite truckish, though not as "tagtag" as the Fort. The Fort has a better second row, and I feel that it drives more securely, but even with the "new" rear suspension, it's still kind of harsh.

The Monty is a good halfway point between durability and comfort. Ride comfort trumps the other trucks in the class (Eve, Fort) and it's more rugged than the crossovers on your list. It's not the best handling vehicle there is, but handling is very predictable and very secure, and the suspension is not as easily upset by bumps as the Fortuner's is. The interior plastic is just a shade behind the Everest (the Fort is pretty so-so in terms of interiors) but the design and execution is leagues ahead. Personally, I think of the Montero Sport as the next-generation Pajero... it's that good.

I think there might already be a snorkel on the market to allow you to cross floods, but on a modern car, I would only cross a flooded street to get to a nearby high point. Once flood water reaches a certain height, there's nothing you can do about it, and even if the Everest's computer box can survive floods better than the competition, having your car go completely under is still expensive.

There are problems with dealerships with any brand. It will depend mostly on how conscientious your service advisor is and if you're on good terms with them. I have had bad experiences with Mitsu service before, but there is hope that things might be turning around with the renewed presence Mitsubishi has on the local market.
