These ways both work fine. The computers with cadence are the easiest because you get continuous realtime information. Personally I like the Cateye Astrale w/ cadence. Yeah, initial installation is a bit more involved than a standard cyclecomputer, but not overwhelming for the average mechanically inclined. Not comfortable with the install, buy from the LBS and I'll bet install is free.
I'm not sure about other brands / makes, but the Astrale requires no calibration for the cadence feature, it's a 1:1 ratio.
