As other have implied, it's all about the condition of the boat; not the nameplate on it. A derelict Morris or Alden will cause problems for you, regardless of where or how you sail, much moreso than a well-maintained Hunter or any other brand for that matter.
One of the reasons most people avoid this forum is the apparent density of self-proclaimed experts who seem to enjoy bashing anything other than what they currently own and I seriously doubt any of them have sailed a Hunter extensively offshore enough to form an informed objective opinion.
I've had the opportunity to cruise extensively when younger and can tell you first-hand that no one anchored in any S Pac motu spend any time talking about which brand boat is best/worst suited for cruising - they all spent all their time talking about repair and maintenance issues regardless of who made it.
It should be apparent to you how seriously you should take anyone who makes generalized criticisms of anything.
