Dendeoscope needs a hypothesis, and interpretation is hard (for the untrained eye). Consensus phylogeny is better. Ultimately we still don't know what the OP wants to achieve

The answer to the question is to do it programmatically via Pythons ETE and use Matplotlib graphing output options to produce multiple plots per diagram. The problem is we don't know how your tree files are stored. So I can put code but I'm not sure if you could modify for your purposes

How would they be displayed? Are you thinking of some sort of multi-tree alignment with the trees superimposed on top of one another? Or do you just want one next to the other?

What exactly are you trying to compare? You can just count the number of sequences in each cluster for starters. With a package like `ete3` you can count the number of leaves, number of nodes etc. in each tree. These kind of stats might be more informative than a visualisation depending on your interest

I recommend using `densitree`: <https://www.cs.auckland.ac.nz/~remco/DensiTree/>

And `rwty`: <https://github.com/danlwarren/RWTY>

Densitree plots the superimposed set of trees in a heatmap-like format: [![densitree](https://i.sstatic.net/6LcOe.jpg)](https://i.sstatic.net/6LcOe.jpg)

And `rwty`, a very powerful `R` package that allows visualisation of treespace in an NMDS format (among other methods): [![rwty](https://i.sstatic.net/S2fsR.png)](https://i.sstatic.net/S2fsR.png)
