sailingdog on this forum owns a Telstar 28 and if he doesn't post you can email him. As far as I know it is a very high performing cruising tri. His opinions are respected here and on his personal site where you may learn more about the Telstar as well. Adrift At Sea
Sorry I really can't help with opinions of the other boats you listed except I would think the Island Packet 27 would be the best built of that group as far as being a solid cruiser.
