But it is the same as Win7 with a few modifications.
I'm sorry, I meant to make this a jovial response pointing out the inaccuracy of this statement... and it turned into a monster. That said...
Sorry, but no. Just... no. 8 is leaps and bounds better than 7 for a multitude of reasons. And I'm not just talking about things you can see (task manager, file copy dialog, etc.). The inclusion of the Server 2012 hypervisor alone puts this OS in a league of it's own. But let me mention core tweaks including secure booting, a nearly impenetrable kernel, faster booting, better overall performance over 7, power management and savings for laptops/tablets, improved Explorer, native VHD and ISO mounting, and other countless other additions that come from the Server side. I could probably double the size of this post with additions and improvements alone. Now that's not to say there are NO negatives about the OS... but the positives far, far outweigh them. Don't even get me started on corporate security and administrative mechanisms. Bluntly, this is the most incorrect statement about 8 I've ever seen. Windows 8 is not simply an upgrade to 7 - it's a complete re-write. MS spent over 10 billion dollars developing 8 and 2012, and for the first time in over a decade (I believe) they even added a core requirement to all new software releases (that it be completely manageable via Powershell.. but don't get me started on how ridiculously amazing PS is).
Does that mean 8 is the best for everybody? Yes and no. I wrote a few different/additional tangents, but ultimately I understand that people are simply resistant to change and learn at different rates. If I need to learn a new OS, I can load a VM and do my due diligence. Unfortunately, that isn't feasible for everybody, and I get it. But if you have the ability to load 8 and spend the time learning it - then you really owe it to yourself to do so.
No, I don't work for Microsoft nor do I own any stock in them. Maybe someday though

To stay on topic, I tried XP 64 to start (machine is i7 w/ 16gb of ram) but had driver issues with my ArcadeVGA and didn't want to bother Andy with it - so just switched to 7. The only reason I went XP to start was because it requires less overhead and I assumed it would have better compatibility. Maybe this would hold more truth if it was the 32 bit variant, but I haven't been active in the emulation community since around 2007 so who knows.
