I makes no difference if you use a mac or a PC, it's all down to what you do with it - you can do basically the same things on each.
It's all down to the person in front of the screen...
These days, PC's are not all that upgradable, if your PC is more than a couple of years old your as well building a brand new PC instead of trying to bring it up to date.
As long as your hardware does all that you need it to do then it doesn't matter if it's a mac, a PC, or a bloomin etch-a-sketch. I'd happily code in DOS if it was all there was, hell the entire tracking system in this semi-conductor factory runs in DOS, it works and it hasn't killed anyone yet - all that converting to Windows would do is make it look a bit prettier, and cost us £300,000 or something like that.
The annoying thing is when people praise the mac, or linux, without really knowing why apart from some glittering nugget of irrelevance, like the shape of the mouse. Not meaning anyone here of course, just this one numpty that I work with who's always impressed by the most stupid of glittery things.
We're going down... in a spiral to the ground...
