My dry suit has had the biggest affect on my diving pleasure and comfort. I went four years switching out different wet suits (7mm, 5mm, or 3mm) depending on the water conditions. Now I just change underwear to suit the dive conditions and dive dry all year round unless water temps get above 75.
If you dive a lot, it is actually cost effective in the long run.
