I have a little experience of Long EZ's which may be useful in this discussion:
I built one, and have about 700 hours in it. I have flown briefly in the backseat of two others and so have a basis for comparison. I have also spent considerable time in other aircraft such as Archers, Citabrias, Gazelles etc.
The perception of Long EZ's as c--p seems to be a personal opinion.
More factually perhaps, the most defining feature of Long EZs is that they are slippery and efficient. This means that you have to manage speed and descents somewhat more than in more usual GA aircraft. So much so that I find that I need to slow up to 75 kts well before entering the circuit, and having done that, I find the rest of the landing process follows relatively easily. Having gotten used to slipperiness, in general handling, the aircraft is positively stable in pitch and yaw and neutrally stable in roll. Stick forces are nicely balanced and a little on the firm side and produce immediate response with pressure. No rudder input is required in flight.
Accommodation is snug but comfortable in the front seat and snug but uncomfortable for tall people in the back seat. Lots of luggage can be stowed but it must be packed in soft bags to fit the odd nooks and crannies. There is storage in the wing roots, main-spar, behind the seats and alongside the rear seat. If fitted, baggage pods capable of adding 20 kgs storage per side can also be used.
Being a pusher with a rather firm gear, means that Long Ezs are not that happy on rough strips and that damage from things kicked up by the nose-wheel into the prop on gravel strips is something to watch for.
With all of the above in mind, I really like flying mine. Of course, if any of the characteristics that i mentioned don't appeal to you, you may not.
