I am looking at this wetsuit. The seams are sealed and taped. Cheaper suits are just sealed (both sound better then my chilly stitched seams). What is the difference between sealed versus taped and sealed?

Also, re sizing, buying on line is tough. The right size for me looks like a 6S but then the neck will be 1/4 inch small. Advice?
