I find the seats on any 777 uncomfortable, but combined with a very large/tall man sitting in the aisle seat next to me, and a normal sized man to the other side, it was a far from comfortable 10.5 hours. [Seat 52E on a Boeing 777-300ER]
If you want to start your trip on the wrong foot uses Air Canada Rouge, you are on the right path.
My friend and I were flying from Toronto to Budapest, we had confirmed seats on Rouge when we first booked, our cruise, with Viking. When we checked in with AC, AC had changed our exit row seats to and had reserved us some leftover seats. My friend is 6'4," his seat did not allow for LEG ROOM not even half of an inch. In this old plane model 767300 ER, AC added some seats to the configuration therefore, there is less space between the seats in the economy class.
While we waiting on the tarmac, it was very difficult to breathe because the airflow was controlled by the pilot and it is only until we took off that he started the air. The food was not just terrible, whatever was served for breakfast was not eatable. Both my friend and I have traveled with many different carriers and this is the first time I have to write such a review. Don't Fly Rouge [Seat 38K on a Boeing 767-300]
Row 1 seats are bulkhead, no footrests and no overhead storage as there is equipment above. Aisle seat C was slightly more comfortable allowing me to stretch legs a bit more than 1 D which had bulkead closer to seat. Once on-board realised that rows 2,3 and 4 had more stretch room as you get your feet under the seat infront of you. Look at photo, we are all still cramped in, I am 6 feet and could not sleep on night flight. Crew for food and service were very good, but do not stop economy from using front toilets, so lots of traffic though curtains were closed. Premium Economy is worth it for the priority checkin, priority boarding and leaving AND luguage should come out first, but did not in Dublin. Poor selection of music channels and movies.

This row `1 seat has the window, terrific for someone under 5'10 as there is no leg rest, no underseat storage and small storage above. Seat is wide enough for regular person. The pitch is acceptable. Again, I agree with spouse that this category of seats are good for the priority checkin and boarding, plus first off the plane and luguage on return was first off. Food from Air Canada was very good, service was top notch with a crew that was in good form. Will be flying again with Air Canada on an Airbus, but never on the Max 8 again. Row 1 means no stretching of legs for 6 hours, behind us they can stretch out under the seats, more comfortable. [Seat 1F on a Boeing 737 MAX 8]
Good seat and only 1 seat away from aisle when needing to go to the washroom. It's what I expected so no disappointment. Was on time and that's more important. Easily beats American carriers, like UA, AA, DL. and way exceeds SPIRIT, ALLEGIANT and those other ULLC carriers. Sorry no pictures [Seat 15A on a Boeing 767-300]
Solid choice, this exit row seat has extra legroom; the seat in front does not recline; no under seat stowage during takeoff and landing; may be missing an armrest; seat cushion may be very firm. [Seat 20A on a Boeing 737 MAX 8]
Better than some but not the best, this exit row seat has extra legroom; the seat in front does not recline; will not recline; no under seat stowage during takeoff and landing. [Seat 19B on a Boeing 737 MAX 8]
