What kind of pricing are you paying and what kind of pricing would you like to see per item?
Bulbs are typically fairly cheap, unless you’re getting ones that support color changes.
It also comes down to developing a plan. If you have a fixture with 2 lights, it is slightly cheaper to go with bulbs (if at full price of about $15 each) than to go with a switch (about $35) and a pair of cheap LEDs ($2 each).
If that fixture has 3 lights, it is a little bit cheaper to go with a switch and dumb LEDs.
For my current place, I felt it was really only feasible to go with switches to control my bathroom fan and kitchen lights (fluorescent tubes). Everywhere else, it made sense to just go with Hue bulbs (old lux were $20 and white are $15 at normal retail price).
It also comes down to time and effort. Do you want to spend the time to re-wire all the switches and outlets? If not, bulbs and pocket sockets get a big boost due to simplified installs.
