IMHO yes, there is a difference in how your bet is perceived when you forcefully say pot or put out more money than is in the pot (with the highest denomination chips at the game). Whether they read it as strong/weak I'd guess most see it as strong, but they definitely all see it as "Cap is ready to pot pot pot if he gets his runout"
You could just ask how much is in there and keep betting your 80% but there are obviously spots where you want max F.E. and have to pot it.
There are other things to consider like:
- most live players have a general sense of the math on a pot sized bet but would have no idea what $135 into $160 is doing for their draws. Double edged sword there.
- Potting has more fold equity. Another double edged sword because keeping them in lets them make big mistakes later
- If you're going to have slightly variable bet sizes, you are going to have to learn to balance them
