A mac will not be superior to a PC, it can be equal to it but cost you more to get there.
Not so. By the time you add in all the inclusions that come with the Mac, a PC will cost the same or more than the Mac. When I bought the current i7 iMac, I looked at buying a Windows box. By the time I took the nearest equivalent Dell and brought it up to as close to the Mac as I could (the Dell system ended up with a 24” screen running at lower resolution than the 27” iMac screen), the Dell as about $300 more.
If you wanted the Dell equivalent to the iMac display then you should have taken the Dell UltraSharp U2711 which is cheaper than the Mac Display. Apple is a bit more expensive that is a fact
The big advantage with PC is that you can buy the component you exactely want. I always customize my PC for my need and Apple can’t give me what I want. And as years pass you can always eventually sell old components to buy new ones. That is harder with Mac.
Now for a valid comparison here is a list of components I’d buy if I was to make an equivalent to the best iMac

The iMac is a bit cheaper, BUT
I get the CPU of my choice. Not sure with Apple
I directly chose 32Go Ram which I can’t with an iMac and that could be very usefull with 3D hungry scenes
Can’t buy an Nvidia Card with 3Go Ram for Gpu rendering with Octane and no Nvidia SLI to get more rendering power
My second HDD is 3To vs only 2To with the iMac
Where is the BD writer option for the iMac?
Bought a good soundcard cause I’m also a musician. Should add 150€ on the iMac if I want that too
My power Unit is strong enough if I want many Graphic Card in SLI. The iMac Power supply is only 310 W. Can’t add a lot of cards
So I’d say that it really depends on what you want. If you want something simple out of the Box go for Apple as long as you have everything you need. Plus I’ve been told that Apple vendors are very nice. If you want to do Gpu rendering with Octane, be able to go multi Gpu, want 32Go Ram you may consider a PC. And you get more power for the same price.
The really important thing is what you need and how you work. I also have a good notebook HP Workstation i7 with 8Go Ram and a Quadro Gfx Card. I mainly work on my desktop but I also work on my notebook when I’m not home. I don’t really know what you mean by “more complex scene” so I can’t tell if a notebook is sufficient for you. I can only tell you it’s enough for most of my scenes till now but I don’t think my scenes are complex
Last point is your taste and feeling. I don’t care about the design of my computer but some people do. On this point Apple is good and their product are well thought and robust. I don’t think I know anybody regretting buying a Mac. So that is very up to you
