Question about the best way to go about serverside and client side in a place system?

So let me explain

I have a placement system ready

now I have 2 choices when doing server side and client side connections

When the player builds and places something I can fire a remote event to place it right away

the second option which I think is better is

after the player has finished building I can fire a table of remote events and load all of the objects in their base.

What do you guys think is generally a better practice to do so?

Basically to summarize it

Option 1 is

When the player places something

it fires right away and places it on the server

Option 2 is

let the player place everything local sided

and when they are finished

Fire all the objects in a table in remote event

and show it on the server

A combination of option 1 and option 2 can be achieved. Option 1 prevents exploits and option 2 doesn't. When the player places something, have it be placed on that client, while also sending a remote to the server which is storing the information about the size of the part, position, color etc. The information is stored in the server but the server isn't creating the object. When the client is finished building, the server will fire a remote to ALL clients with all the information sent from the first event, and then it will replicate to all the clients, reducing the server load, and making it exploit proof. Of course you can edit the system I presented to what you want to achieve like, if you want it to show up to all players while the player is still building etc.
