I've flown the EMB-145 several times EWR-PIT on CO. They're far mroen comfortable than a prop, though not spacious. Insufficient carry-on luggage space (necessitating gate-check for anything even medium-sized) is my major complaint. A major plus is that 2/3 of seats are aisle, AND 2/3 window (3 across)--get the single and you get the best of both worlds. Legroom is average.
