A flat grind is not a weaker blade, in fact, in most cases it is stronger than a hollow grind simply because there is more metal on a flat grind.

I agree with Nighthiker but maybe not for the same reasons. I'd get the Howling Rat because it's cheaper. Then I'd order a Mora or two to go along with it. But if price is not your primary consideration, then I would get the Ritter Mk3. I wouldn't go so far as to say it's a better knife, I own neither so I couldn;t do that. But, being a Benchmade fan and an owner of several, I trust that the Ritter fixed blade is high-quality and a step above the Swamprat.
