If you are looking for pure daygaming options, pretty much all EE countries have equal volume, adjusted for their population sizes. I can't think of a single car-dependent EE city, with probably only Moscow punching below its weight for pedestrian volume since car culture there is by far the strongest in EE. Cities with strong tourism industries like Prague, Budapest, and Krakow will obviously have the highest pedestrian volume, at the expense of a less "pure" EE experience.
If you are looking for what country will yield the best results with the most little work daygaming, then that in my opinion is a fruitless question.
Pick a country that you think you'll enjoy the culture and people the most. Then go there for long periods of time, as long as you can, try to make some local friends and learn some of the local language, and then game by adjusting to the local situation of the Westernization of girls and/or the friendliness of the guys.
If you detest a country or city for some reason, then find a different one. If you go in with this mentality, you will eventually crack the code for any country, but it will take time, effort, and most likely frustration initially. Keep in mind that I can give you a laundry list of problems for every single city in the world. Nowhere is perfect, but you can (and encouraged to) leave if you definitely think the girls and the general vibe is really not for you.
