Depends on how stressful the driving is. I used to commute from my hometown to the metropolis about an hour away a few times in my life. First, for internships, when I had to be there at ~9:00, and driving in traffic, it was 1.5+ hours each way with a ton of stop-and-go. My first car - '84 Jetta GLI, 5-speed with no A/C in one of the hotter summers that decade. 3+ hours home one Friday.
Much later, I had a job in a different part of the same city, but with a startup, and I was able to set my own hours, so I'd leave around 11:00 am, go home around midnight (was still single at this point) and it was an easy 60-65 minute cruise at 80-90 mph (and still getting passed left and right by pickups). Of course, gas was cheaper then, I didn't have a family, etc. Edit: those two commutes weren't even remotely comparable in terms of mental toll.
These days, I'm taking express lanes to cut a 45-60 minute 20-mile trip down to 25-30 minutes, because stop-and-go is tiring (especially these days - seems like the average driver is way more distracted / worse than 20-30 years ago and there are more of them!), and I have a family, etc.
So, how tough the commute is also matters, IMHO. 45 easy minutes where you can relax, listen to some tunes and basically cruise is better than 15-20 minutes of ***holes cutting you off every chance they get.
