I used a set of the Halo key skewers for a year or so. Not bad overall. Probably very, very marginally more aero than an aero quick release set. Never had any problems with slippage or anything. For under $20 I figured it was worth a shot with them.

Use and love the Halos. Cheap (much more so than things like Zipp aero QRs), reliable, light (you can remove the steel anti-spin washer if you want), lots of color options. I use them on both my road and tri bike for day-to-day (just have the allen key in my flat kit). They look sleek, match the bikes, and provide a bit of extra theft protection vs. a std quick release.
As for titanium, it is lighter and weaker than steel (both by about 40%). In theory you could make the steel rod thinner than the Ti one and weight would be about the same, but in practice they are usually the same (the steel is just overbuilt). Ti does have more of a tendency to gall Al threads, but you don't really unscrew them that often, so it may not be an issue in practice. You can wrap the threads in PTFE "plumber's tape" ($0.99 at any hardware store) for extra thread lock and galling protection.
