I have two models. The first one put much more restriction on the connection between the variables. The second model, however, provides much more flexibility for connecting the variables.
I would like to express my sentence without repeating the words.
Model A requires a specific connection between variables. Model B, however, offered much more free in connecting the variables, which provides much more flexibility to the multivariate models.
I repeat the word much more, which makes my sentence wordy. Can someone help me to express my sentence in a good way, please?
