It’s like why some vehicles are small and light (car) and some are big and heavy (big TRUCKS for cargo). Different things for different circumstances.
Eggs work for some circumstances but other times not. Some species do one thing and others do different. The other comment has some good info.
Also you should look up egg-laying in Wikipedia or on Google. Scientists have a lot of info about it.
