Lodges in Ruaha and Nyerere for wildlife viewing

We are planning 4 nights each in Nyerere and Ruaha and trying to decide on the best lodges in terms of location for wildlife while keeping an eye on the budget and had the following in mind: Ruaha Ruaha River Lodge Mwagusi Camp Mdonya Old River Xamp Nyerere Rufiji River Camp Lake Manze camp We will probably stay 2 nights in each camp across both parks Any experience on these lodges or recommendations for lodges that are good for wildlife viewing and fall in this price range would be appreciated.
