You don't have to worry about UE4's performance. It has the best performance I've seen in a game engine. Ever. I don't think Unity is faster. In fact about 3-4 years ago when I tried Unity out I was overcome by how slow it ran on my machine vs Blender Game Engine.
The engine fan boying UE4 gets sometimes is annoying, I use it and really love it, it has a lot of things going for it, and a great community, but it isn't the best fit for everyone.
Regardless of the engine's capabilities that both have...you have to consider Epic's support for prommoting games has been really good since i rememeber, specially now with UE4.
Really with any package or engine, max and maya can both easily duplicate objects around splines, and Unity could do it via a editor script, while unreal can do it via a construction blueprint.

Everyone is entitled to their opinion. No need to call names. I haven't really gotten in to any ready made and branded game engines since I am working on mine and waiting in the slightest glimpse of hope for ubi-arts game engine, I would prefer to use unity because I am already studying c# and you can write scripts in c#…
I'm sorry if I came off as overly rude in that post. In hindsight I shouldn't have made it. But I don't believe that your no-holds barred, UE4 is the absolute be-all end-all of every engine ever made attitude is conducive to being used as a source of advice, or discussion, and you've used it repeatedly throughout the…
