I have both imperial AT-AT walker kits from tgese two companies now. And this new addition to aid my diaromma focus. 
Act 2 kit is said all over the web to be scale 1: 100. 
Bandai scale in 1: 144 on the box. 
The AT-ST is a a dissapointment. 
I expected an interior cabin which it does not have. 
So, fabricate it....yeah but...
Bandai's AT-AT in scale 1: 144 is LOTS Bigger than this weasley AT-ST chicken walker. 
From popular well made video games its much taller, wider, & longer , so this can't possibly be correct & Bandai should label their box as such. 
Snowspeeders: Bandai's hands down is better. 
My dilemma is that Act 2's scale 1: 100 snowspeeder is smaller than Bandai's 1: 144. 
If your on a small budget & can't afford all these kits, you pick one. 
If you buy Bandai, you must buy 3 kits total just for one walker, two snowspeeders, two AT-ST ( which will only look half correct off in the Distant backgrond  ). 
With Act 2 one kit provides one AT-AT ( Larger than Bandai's 1: 144 ) , two snow speeders, & two Rebel base Laser Turrets. 
Bandai's scale 1: 144 AT-AT is incredable. 
Act 2's is prety darn desent. 
How well can you paint? 
1/ 144 scale figures are provided in Bandai's AT-AT kit. 
Known in Act 2's 1: 100 scale kit. 
I was aiming for a highend diaramma build, sculpt, with model kits I expected to provide tons of detail. These are my 1st chance working with scale 1: 144 figurines. 
I'm not convinced Bandai got them to correct scale. 
As a seasoned modeler, fabricator, brush painter, & a beginning airbrush user looking forward too wiring & lighting my diarammas - I would have seriously appreciated both companies coming forward with more details in relation to their scale focus.  
This AT-ST should be much larger in 1: 144. 
I'll likely buid mine from scratch now. 
Bandai either made their 1: 144 snowspeeder over sized ( larger ) or Act 2 made it's 1: 100 snowspeeder undersized ( smaller ). 
If your into mm; 
1: 100 = 15mm
1: 144 = 12mm
