Lightbright, to answer your original question, you’re right that same kinds of themes that are emphasized in chassidus (such as joy, faith, love of Hashem, etc.) are also found in the non-Chassidic Orthodox world today as well. Some versions of Litvish mussar are quite similar to chassidus in their overall emphases. Often MO or Litvish rabbis study chassidus or quote chassidic teachings in their drashas. And many chassidic bachurim go to Litvish yeshivas. So there’s a lot of mixture nowadays. Most people stay in the group their parents are in and are perfectly fine with that (though perhaps some of them feel uninspired and would benefit by venturing out a bit to other paths within Orthodoxy.)
Even 100-200 years ago the stereotype of the Warm Chassid and Cold Litvak weren’t exactly true (there are very spiritual seforim by Litvaks, like R’ Alexander Zuskind hundreds of years ago for example), but now it’s probably less true.
I personally gravitate toward chassidus as you do (especially Breslov), but I also appreciate the teachings of many non-chassidic rabbanim like Rav Hirsch and the Litvish rabbis I know. Everyone is different, and it is often said that people’s neshamas naturally gravitate toward certain approaches that appeal to them and provide them what they need at that time to grow closer to Hashem. Hope that makes sense!
