Well, I like a lot of Polish names, but I dislike the Polish spellings. For example I prefer Viktor over Wiktor, Matteus over Mateusz etc. Some that I do like:
Amelia
Ariadna
Celina
Halina
Ilona - a family name for me
Klara
Damian
Dominik
Edward
Emil
Filip
Gabriel
Joakim
Kasper - I see it as more Swedish than Polish though
