It really depends on what you want the knife to do, and how much that is worth to you. One of my only Cold Steel knives is a Recon 1 tanto in AUS8. I bought it based on the vast number of positive reviews I'd read, without giving much thought to the practicality of actually carrying it on a regular basis. Well, it's a big knife, the clip is extremely tight, and the G10 texture is pretty aggressive. These factors ultimately kept it out of my pocket. However, I have heard that the new XHP version has less aggressive G10, and is a little lighter.
Meanwhile, my only Emerson is a Mini A-100, so I can't really comment on the Roadhouse, but it looks like you could choose a blade that's either a little shorter or a little longer (on the Super model) than on the Cold Steel. The Emerson will be heavier, if only because it has titanium liners while the Recon 1 is strictly G10. I have no issues with the G10 texture or clip tightness on my Mini A-100, but couldn't say how the Roadhouse compares. Either way, you're looking at some pretty big knives (which is fine) with one costing twice the price of the other. You can chalk some of that up to US construction versus Taiwan, but 154CM versus XHP is a more tangible point of comparison I think, as the few Cold Steel knives I own a quite good in terms of workmanship. My Emerson needed a lot of breaking in, to the point that I almost returned it out of frustration.
I guess I like the look of the Recon 1 a lot more than the Roadhouse, and ultimately would buy it if the G10 is less coarse than on the AUS8 version, but that's just me.
