The Rover engined Plus 8 is great for long distance trips as that V8 burbles along effortless all day long. I'm 6 foot and find it very comfortable although there is a knack, like all Mogs, to getting in and out. The only possible downsides are fuel consumption and the footwell can get hot, especially in hot climates.
There'll always be some compromise with a trad Morgan, no boot, not the most rainproof etc. so if you want comfort a modern tin top would be better suited.
