When using a heat lamp, doubly secure it. A heat plate is a safer and lower wattage option.
we often use both. Newly hatched quail couldn’t keep warm for the first 4 days under a heat plate-they needed a heat lamp. Then they were fine with a heat plate. chicken chicks are fine from hatch under a heat plate.
I often use a heat lamp for 1-2 days on chicks that are on puppy pee pads in the brooder. This way I can easily observe the chicks activity, and see any mobility issues quickly. Also, I can easily see any poop issues. and they only have food and water, so they are not trying to eat the bedding. Once they are 2-3 days old, I switch to a heat plate and shavings.
so, which is better depends on your style! Both can work well for keeping chicks warm.
note on heat lamp bulbs: only use ones rated for livestock. Others may have coatings on them (like the ones for foodservice) which will off-gas toxic fumes that will kill your chicks/chickens. So, if you are buying at a feed store, they should be the correct ones and will note on the packaging that they are ok for livestock.
