I would suggest you join/visit irv2.com forums and read both the Newmar and Entegra coach owners forums. IMO, both Newmar and Entegra make great DP's. Entegra did have some real quality of build issues about a 1 1/2 years ago but, according to what I have read on those forums, they have addressed that.
The Aspire does not offer IFS (independent front suspension) and I believe that is standard on the Dutch Star. I've had DP's with both and, IMO, IFS provides superior ride and handling. Some folks swear by comfort drive but with most tag axle coaches, unless you have some suspension issues, they generally handled very well.
Newmar does offer factory delivery for a new coach and I don't believe Entegra does at this time. IMO, factory delivery is the best way to buy a DP. Also, any of them build a dog once in a while so be prepared to spend the first year getting the bugs worked out of any new coach.
Finally, I don't believe the last brand you mentioned is in the same league as either Entegra or Newmar.
