Both are nice. I personally like the look of corgis better though. However, they can have major health issues like intervertebral disc disease and canine hip dysplasia (I don't know exactly what those are, that's simply what a quick google search told me because I vaguely recalled something about corgis having something like that). Pugs, on the other hand, can have way more health problems. So as long as you're careful while playing with your corgi, corgi's seem to be the best bet (in both looks and health tbh in my opinion).
However, a trip to your local pet shelter, like the SPCA (where I adopted my cat, Kali from. She's seriously the sweetest cat I've ever met <3) couldn't hurt <3
