OK...But I'm not really into opinions on things, especially to do with safety. The fact is waders don't fill with water, when the chest/waist strap is cinched. And my experience, being pitched head-first out of my Kayak in deep water was that very little water came in, and that was with the straps un-done.

The fact is it doesn't matter anyway if they "fill" with water, since it won't drag you down anyways They FLOAT YOU.

Wetsuits are uncomfortable, and COLD when worn above water unless covered in some sort of wind-proof layer, and then they are effectively waders.

Waders are safer and warmer, more versatile and more comfortable.

*fact*

That's why the professionals wear them, and so do I.

But do whatever you want, by all means! It's your right and you should do what you are happiest doing. It's just that a million opinions don't change a single fact... :-)
