Defender or Hunter?

Here's another one of my army lists based on eCaine.  Unlike my other army list, this one uses a Hunter instead of a Defender.  With the extra points, Caine can take the B13 - which is a great toolbox unit plus the fact they do quite a bit of damage.

Points: 35
Captain Allister Caine  (*5pts)
* Ol' Rowdy  (9pts)
* Squire  (2pts)
Arcane Tempest Gun Mages (Leader and 5 Grunts)  (6pts)
* Arcane Tempest Gun Mage Officer  (2pts)
* * Hunter  (6pts)
Black 13th Gun Mage Strike Team  (4pts)
Rangers  (5pts)
Captain Arlan Strangewayes  (2pts)
Eiryss, Angel of Retribution  (3pts)
Reinholdt, Gobber Speculator  (1pts)

So I guess the question is:  Defender or Hunter?  The Hunter allows me to make AP attacks vs. Medium-Large base models (halve their armor) and can do the same damage to those models as the Defender.  Add in some Runeshots from the marshaled ATGM UA and you've got the same amount of tricks as the Defender.  The downside to that is that against small base models, the Hunter only does 8 damage vs. the Defender's whopping POW15.  On the plus side though, the Hunter has AD, Pathfinder, RAT7 and DEF14.  Since it can move freely in terrain, it's basically floating around DEF16 and is an excellent harassment tool.

The Defender, on the other hand, has more damage boxes, more armor and a RNG16 POW15 cannon that shoots at RAT6.  He also has a MAT7 Cortex Hammer that can hit for a respectable PS16 and does 1 point of Cortex damage with each hit.  Since he does equal damage all around with his cannon, he can reach out and slap vulnerable warcasters/warlocks for a shit ton of damage.  The 16" range also allows the Defender to aim at most targets for an effective RAT8.

The big thing to note about these two is cost.  At 6 points vs. the Defender's 9, taking the Hunter gives me the B13 or A&H vs. the Defender + Stormsmith.  So far, I've been having good success with the Defender, but I guess I have to play around to see what's good and what's not.
