I looked into the RB 200 when I was going through the process. I say get the bay boat.
I would consider:
You are not far from some interesting places, and even though you say small lakes and rivers, the intracoastal is right near by. The bassboat will have issues there. Not with the waterway itself, rather the large powerboats that send off huge wakes. The bay boat can go in the intracoastal though and do just fine.
If you plan to take more than one guest, the bay boat will be more accommodating to seating.
Each boat has plenty of storage for fishing gear. Each can be setup to troll pulling or pushing.
The dealer nearest you has a couple of Rangers but mostly sells Tidewater boats ($$$). I understand that it is a tough time to be getting a new boat as everyone blames the flu for not having product. I was told that I would be waiting until May to get an engine for a new boat sitting on a dealer’s lot. You might find that ordering your boat will take a while. Be sure to look into availability as it may change your mind.
Kind of hard to choose a boat without ever being able to sit on it. Getting on the boat and spending a half an hour playing around is important to making sure the boat is a good fit. If you are set upon a Ranger, I recommend driving to the one you want. I drove to Tampa and Deland and Orlando looking at boats. Eliminated all of my top five list that was based on internet sites. Each fell away due to something or another I didn’t like. No boat will be 100% perfect for you, but surely there is one that will be 90% what you want. You are going to live with it for any number of years and those will be good or the boat will stay in the yard.
I think I made a good choice when I bought the 20 foot Xpress bay boat. I took it up a creek that was about five feet wide and a foot deep by lifting the trolling motor up and the boat brought my wife along nicely behind. We made it into the Black Lagoon which only kayakers access. I was amazed. We plan to run the intracoastal and catch mullet and flounder. Explore the St Johns and find springs and catch shrimp and crabs. Pull tubes in Summer. Scallop in the Gulf. Do this and that and so I picked a boat that could do all those things. When we ride around and when we fish we almost never bump into one another. I set her up with a nest on the back and she reads while I fiddle and fight my experiments. Plenty of room no matter what we choose to do. Very happy that I didn’t get a bass boat or a fiberglass bay boat.
Ranger made a great name for themselves, but times change and I read a lot about how problems with the various boats get addressed. Dealers blame manufacturers and manufacturers claim they never make mistakes. Ranger is part of the White River Marine Group now and you will definitely want to look into all of this before going with a $30,000 purchase. The dealer looks aggressive to me so make sure he doesn’t push you into the boat he wants you to have. Take your dear sweet time and it is OK to be an unfriendly customer.
