Top raids dificulty progression?

[Kika Maslyaka]

I am curious how would you guys place the progressive difficulty of top raid mobs?

From Vox and Nagafen to Planes, to Trakanon?

I suppose Nagafen will be at the bottom of the list, then Vox...

I didn't do original planes during classic, only after they were revamped (around past Velious), and by that time Trakanon was a complete wuss, while revamped CT in Fear and things like Bzzt in Sky were simply murderous.
