Personal opinion -
With all boats I think it depends what you want your boating to be - where, what sort of waters, how many people etc.
There are many good 'plastic' boats on the market and pioneer are a well known brand often used by sailability groups due to one of the model having a 'drop down' door on the front. Although a different model a bit of information for their groups is available here

Pioner have a reasonable reputation, 'plastic' boats are perhaps not as comfortable a ride at speed but depends on seating maybe? We have a rigiflex and find it very stable and capable but not the most comfortable if 'speeding' about!
