Archie,
Welcome aboard!
There are users here of most vessels in the 16’-19’ range.
As you probably are aware every boat is a compromise depending on the planned use and price. The Warrior is probably the most expensive in class however it is also the best in class in terms of build quality and resale value. I have seen plenty Explorers and they seem to be a fine craft with similar lines to the 165.
Have a look at this site:
http://www.fishing-boats.info/ There are plenty reviews for each class and make of boat. Most reviews are copies of reviews that have appeared in magazines.
If you have further, more specific queries, post them up.
