Not exactly what you are looking for, but I wrote a USA Road Trip Guide a while ago. I have never been on such a long trip, but I remember driving in Canada was very easy. However if you are not the most confident driver, stay away from big cities. Quite frankly Montreal was one of the hardest places to drive and to park your car. Maybe you should park and ride if you plan to visit those cities. Montreal has pretty good public transportation (which I didn't use). I paid out of my nose for parking.

Gasoline is more expensive then in the US. If you rent a car, get one with excellent Gas Mileage. Plan your trip so you avoid traveling in major urban areas during rush our as much as possible and you should be fine. Not much to worry about.

EDIT: Today I got myself the Mio C310x GPS Navigation System at Fry's. I was actually there to check out the deals they had on the Garmin, but then I saw the features of this unit and it was cheaper than even the most low end Garmin. Anyways, its pretty good. I drove quite a bit today (Gold Country, Highway 49 ..) and it was very accurate and fast to guide me. I guess something like this makes a lot of sense for road trips.

My car gets over 30 mpg on the highway, so gas will only be horribly expensive.   Thanks for reminding me about the cities.  I'd forgotten about that.  I've been to Montreal, so I was thinking Quebec City.  But since it would be a road trip, I might just skip the cities altogether.

Of course, I may never go.  I plan about ten trips for every one I take.

Don't skip the cities, just park outside and take public transportation. I think Quebec City is well worth the visit and you would really miss out not going there.

If you really don't like driving, you might consider one of the scenic train rides. I know they offer them in Canada, I am just not sure if they do where you want to go.

I have this DVD somewhere about train rides in Canada. Maybe I can dig it out and check.

Might want to consider this for a few days since you can see a lot and you don't have to drive.

I think Radar Detectors are illegal in Canada. I know you won't use them, but I have been advocating them a lot so I think its only fair to mention this here. You might also want to check if you can use a cell-phone while driving or if you have to use a hands free device. Many countries don't allow this anymore (and I must say I approve).

Back to your original question on which is better, I would say neither. In the summer it is hot and humid in either of them and I think you might be better of visiting the west (British Columbia). But thats just my personal opinion. Don't let me distract you from your plans.

I usually take a road trip up the east coast to visit friends.  It ends south of Boston, so I thought I might add a Canadian loop.  That's also why I only want to spend a month.  This road trip will be an add-on to a trip that takes me six to eight weeks anyway.

However, I now think I will return to the US this fall for a couple of months, rather than wait until late next spring or early summer.  As far as I'm concerned, the north is out of the question then.  I'll rush up to the Boston area for my visit, first thing, then start heading back down south.

Do see Quebec City if you get the chance. It's not quite like any of our other cities.  It will be celebrating its 400th birthday next year and is the closest we get to a real medieval city in Quebec.  They have recently unearthed some of its original walls.  You'll eat well too, since there are many charming, if slightly expensive, restaurants.
