While I refuse to pay actual cash for a t3 machine, I really like the looks of the thunderchild. However, while I do like the looks, at the end of the day is just that, looks. For 120k dil (which can translate to about 1000 zen), do you think it the thunderchild's Phaser Point Defense is worth it?
And I know it doesn't have to be on the Armitage. Right now, aside from my armitage, I also have a multi-vector patrol, Steamrunner retro, and Ambassador retro.
If you really like the look, you can change your Armitage to look like a Thunderchild after you have it purchased.
I've found the Point Defense hugely useful in leveling chars, and on fighters, but I typically don't use it on level 50 standard ships, as I usually have too many universals that boost stats (Borg console, Rom console, etc.) or are ship specials to leave it on very long after hitting 50 on most builds.
