Yeah. I see the same posts as you about trouble with Windows machines. I'd call them Varneygrams but that might get me in trouble. Anyway, all I can say is that they don't mirror my experience.
However, this makes a degree of sense. When you buy a Mac, you buy a package. Apple make both the hardware and the operating system...and they at least attempt to control software and peripherals you can use with them.
With Windows, there are probably hundreds of different companies assembling the hardware then slamming in an image disk of the operating system. Some use good components and are careful on their software installs; other less so.
I strongly suspect the reason I haven't had trouble is that I take the time to research the manufacturers and models I buy. My most recent machine was a Lenovo laptop and they allowed me to specify the configuration I needed. This effort paid off because I unpacked my laptop, installed Audition and some M Audio drivers, plugged in the Firewire and loaded a 33 track session I worked on in the old machine. The new one worked flawlessly first try and only got better when I did things like turning off foolishness like animated screens and drop shadows on icons.
The big difference with Mac, of course, is that you don't need to do the research. Since they control the hardware and software you KNOW it's going to work together. However, you also pay a price for this control. My Lenovo cost me a bit over half the price of a similarly specced Mac--which, for me, means it's worth the time and effort. (And, as I say, for me it's largely a one-off effort. I've not done anything since the initial purchase.)
It's horses for courses.
In this case, the OP asked if a Mac is easier to record on when he only does sessions occasionally. If he's used to a PC (and that's only a guess of course) and isn't having any tech problems, then a change to a Mac will just mean learning a new OS--and he'll still have to go through the process of re-learning his DAW each time. That won't change whether he's on Mac or Windows.
