Difference between 4443 Stealth Port and Stealth Proxy

First time poster, long time lurker.

I love torguard. As someone who lives within a country that has a strict firewall, its a lifesaver just to be able to check my email. As the title says, I was wondering about the difference between having selected 4443 port vs using the stealth proxy that can be selected by going to settings->proxy->stealth proxy? If I solely select the 4443 port and not the stealth proxy my connection often drops, on the other hand, the stealth proxy usually drops connection every couple of minutes. So does selecting one over the other give me a more stealthy connection?

Thanks
