Can not please everyone but I will defiantly stake that the PS5 design will cause more issues with people and possible issues with manufacture and build quality and cooling with it, especially with the early version from everything I have seen.
It also seems to lack the ports and you CAN Not expand on the storage is something that will also matter I think in the long run.
I would be amazed if they haven't learnt something from the issues with the PS4 hardware and cooling, but it all remains to be seen. I'm unlikely to be first in line for either system as the first batches always have problems - my first Xbox One X was hosed, we all remember ring of death, etc - but in any case we will find out soon enough.
Also you can expand the storage, not sure where you got the idea from that you can't (it would be crazy not to!)
Sony has opted to allow PS5 owners to expand storage using SSD drives that meet its spec for performance. It’s not clear how many drives will even meet this baseline at launch, but it does mean PS5 owners will have greater storage options eventually.
With the X Series you have to have
proprietary cards for expansion, another move that smacks of Sony rather than MS
I'm not surprised by this in all honesty though, those pointless 'game drives' have been around for some time now, but reading into it in both cases this seems to be to offer optimum performance linked directly to the new architecture, so it's not quite the same thing. You can still expand the Xbox with traditional USB storage but it will be slower.
What is great about both is that they are really pushing the boat out to make these devices truly standalone from PC in terms of architecture and where performance matters, its no longer going to be equivalent to say PC master race because they are not like for like. Its going to be as revolutionary as the first PlayStation.
