Wide-body aircraft aren't as comfortable now because of the increased number of seats abreast, but wide-body and narrow-body aircraft sure beat cramped regional jets! I remember flying on an American Connection ERJ with an aisle so small that one passenger was audibly complaining. Aside from the seating, however, I find regional jets quite nice. However, wide-body aircraft are also nice because some are equipped with personal entertainment systems, even in economy class
