There are resources like https://voat.co/subverses where you can sort subverses or search for what you're looking for. Voat is still relatively small so many of the more esoteric and single purpose subreddits do not (yet) have good replacements, so I would consider this if you're thinking of dropping reddit completely.
Don't find the ones you read and reply to, find ones you give content to and help build the sub, its early so using this place to just read and reply is gonna be a while, we ALL have to contribute content to the subs we want to grow the most

It all depends on what you like!
Some subverses I've had fun reading are /v/books, /v/gaming, and /v/ideasforvoat , but these pertain to my interests.
