The problem is that CONCOCT takes too much time to run and its a bottleneck on my analysis, would you suggest me a binning tool with a demonstrated good binning results that is easy to install and fast to use?
With all due respect: do you want to get this done fast, or to get it done right? We are not talking about days that it takes CONCOCT to bin metagenomes, but rather minutes or hours at the most. Pretty sure that metabat2 will bin any dataset in under 2 minutes. Don't have much experience with vamb beyond testing it a couple of times, but I thought it was fairly fast.
I wrote a binning tool that I couldn't recommend to you, because it is not fast. On most ordinary datasets it takes 30-60 minutes, but there are datasets with 9+ billion assembled bases and 300+ bins on which it might take 10-20 hours. Yet I do not care about the time it takes, because the computer does all the work and next day I just collect the data.
Unless you goal is to process hundreds of metagenomes per day over a long period of time - other than JGI and a few sequencing centers I don't know any entity with this need - I suggest you stick with the proven tools you already have. Better yet, to do things right it might be a good idea to run all the binners and find their consensus.
