I've never used an actual Chemex, but I do quite like other pour-over coffee makers. They're convenient, and much more controllable than auto machines.

I find that areopress tends to make cleaner coffee - if that makes sense - and that the flavours come out more. Especially certain kinds of coffee it's nice to let them brew longer - french press / cafetiere style. The areopress can do that easily (inverted style), but the pour-over ones can't.

If you want, you can use an areopress pretty similarly to a pour-over, by simply not pushing down the plunger and letting gravity pull the water through.
