Planning on getting Penn Fierce 4

My 3000 Penn fierce 2 I’ve been using for 6 years has finally met its end after landing a bull red. Planning on buying its younger brother the fierce 4 and was wondering what the upgrades it has from the 2. Is it sealed? smoother than the 2? etc. etc. I’m planning on buying the 3000 and using it on my 6’6 medium rod. I mainly do inshore saltwater fishing with occasionally pier fishing
