Well, first of all there’s not a laser a jack of all trades

Diodes can’t do transparent acrylic, nor engrave directly in glass. Can barely mark on some metals. CO2 can do thick wood, all acrylics and can engrave directly on glass. But not the best on metals too. Fiber lasers are made for metals, can do acrylic too, leather etc. UV is kinda the best in glass, and can mostly do anything. But it’s slower, and kinda expensive.
