Longer wheel base will not make a faster bike. In theory, a longer wheelbase will make the bike more stable, but less "quick". The difference here is negligible though.
520 is just a name-brand 4130 I'd call it a wash.
A higher bottom bracket will leave you sitting higher on the bike, and in some cases, more bent over. Given the short head tube of the cross check, overall position would be similar here. Center of gravity would be a little higher on the Raleigh though.
I'm not sure why the bottom bracket of the One Way is so high. Some people will want that on a fixed-gear, but it's even higher than on the Rush Hour.
Personally, i like the One Way and you're happy with the stock build I think you should strongly consider it. I guess I'm a little turned off by the hype surrounding the cross check. I don't think it's entirely deserved. What the CC does have going for it is the ability to build it up from a frameset if you wanted a custom build. I think you'd have to work pretty hard though to build a CC up for the street price (not msrp) of the One Way.
