What would be worse for a player: 1000 models in ReplicatedStorage or 1000 models in ServerStorage?

So I'm working to optimize my game, and I found a major source of lag. The problem is that I have 1000+ models in ServerStorage that need to appear on the client as a 3D Gui. However, the client cannot access ServerStorage so I did a bit of hack-y work to return the models with a RemoteFunction.

function game.ReplicatedStorage.THREEDModels.OnServerInvoke(plr,model)
	local m = game.ServerStorage.Morphs:FindFirstChild(model):clone()
	m.Parent = game.Lighting.ModelCloningFolder
	game.Debris:AddItem(m,.1)
	return m
end

This gives the client enough time to grab the model before it is removed from lighting. However, it is extremely resource-intensive which is what brings me to my question: How would those 1000+ models affect the players loading time if they were in ReplicatedStorage as opposed to ServerStorage? All help is appreciated. Thanks!
