Back when i worked at a bike shop it was hard to beat the value of a Raleigh. I think the trick was they did not do the big of an advertising campaign like the "big names" and they also have no team to sponsor (ie. pay for). All this money saving would translate into more bang for your buck to the customer. Dollar for dollar you got more bike for your money. To my eyes it looks like this still true.
You will likely never wear out a bike frame (different than breaking a frame). It's the nuts and bolts that wear out or fail. This is where you want to spend your hard earned $. Right off the bat I notice the Raleigh has disc brakes and Truvative cranks. The Redline has Tektro rim brakes and a generic crank (lower end components).
I've been out of the industry too long to recognise every component brand name regarding rims, tires, this and that and so forth. My advise, take a close look at the wheel construction, are they single wall or double wall rims, do the spoke holes have eyelets (grommet reinforcment), are the tires quality or generic? Look at the pedals, all plastic or alloy? An aluminum frame will transmit more road feel than a steel frame.
For recreation i used to recommend steel road frames to people as steel frames will absorb some road imperfections. An aluminum frame with high pressure tires will transmit every little bump to your ....rump (and wrists). At the lower end of the price range, there may be negligible weight savings too if that is a concern.
