Lots of ways to skin a cat LVCHG, VS, OPN DES/CLB.
IMHO as an old school guy I like to control my vertical rate and not let the aircraft dictate it by a speed for vertical control. I use VS quite often and make simple calculations as has been mentioned; gives you nice smooth vertical path. From my military days we would set pitch angles from AOA indicator. Basic pitch and power seems at time to be a lost art in today's computerized vertical guidance, which is a nice reference not the holy grail.
Boeing LVCHG does not chase the selected speed or path as bad as Airbus with OPN Mode,CLB or DES; which can at times turn into a real roller coaster ride trying to chase speed all over the sky.
