The only selling point for NMM is the flagging of mods that have a Nexus update which I would like to see BASH do. The major downside to NMM is the lack of control over mod file priority. This is important for graphic or script mods as earlier files are overwritten by later installs with NMM. BASH shows what files a mod is going to override and what files have been overridden (AKA conflicts). BASH not only allows you to order the ESM/ESP files, but also the installation order. Now I have complete control over files and EM/ESP files that NMM only partially allows. If you take the time to learn BASH, you will have a much more stable game. I currently have 244 ESM/ESP mods activated with 251 total mods installed.
