I prefer rechargeable alkalines myself (such as Rayovac Renewal). They
have the same nominal cell voltage as alkalines, charge quickly, have
excellent shelf life, and no memory effect.
The downside is that their total charge is somewhat less than a standard
alkaline, and that I believe the number of total charge cycles they can
take is less than NiCad in general. Still, for something like the RCX, I
find them ideal.
