I personally like the community a lot more... though I suppose it also depends why you were banned from reddit as to whether you'll be happy here.
If you were banned for talking shit on minorities, trans people or something like that, you'll probably find yourself quickly banned from most instances here. Unless you just avoid the topics
If you were banned for say, being a fan of Luigi Mangione etc... You'll probably be very happy here. Point is lemmy admin's in general are very open to the left, and very accepting of more or less anything but intolerance.
If you were banned for non political views... then I guess it depends a lot, You can talk far more openly on topics of piracy etc.... in most instances.
