Set aside a few weekends and mess around distro hopping. Think of it as a small scientific study. Use what you determine to be the most comfortable with.

I suggest being clever in your partitioning keeping /home and any other areas personal to their own partition if not their own disks. If you want to experiment you lose nothing by wiping / and installing something else. Also, you should decide on an effective backup strategy.

Veracrypt. Make a file on your disk.

Don’t want a storage file?

Make 2 partitions, put veracrypt portable exe on the first normal storage partition. (fat32 is likely ideal here) Second partition formatted with veracrypt.

You still don’t read.

You asked a simple question about “better” which is pretty subjective for whooping out the references along accusations of falsehood.

“virally open source”

Which answered the original question quite succinctly. I wish you would have read more carefully before…
