It's about 1/72 like all of the Koto Variable Infinity kits (excluding the new Steel Haze and upcoming Nightfall/Loader 4, which are closer to 1/35-1/40) and is a bit taller than your average MG. As for it being good... well, the VI kits have always had a reputation for being a massive pain to work with, and while they've fixed some QC issues in terms of plastic quality over the years, the design of the parts and the kits themselves leave a lot to be desired; unfortunately, this kit in particular is infamous for being one of the most difficult. However, that doesn't mean it's not good: The articulation, fine details, and game accuracy are ludicrous, and this particular version of the design fixes a lot of the issues that the older ones had in terms of plastic quality and defects and also comes with enough extras and total runners to warrant the high price. I'd say if you're a big AC fan or just really like the design, go for it, but just keep in mind that it's probably going to need some patience and TLC to really shine; if you can handle that and already have some more difficult kits under your belt, then you might just end up with a true centerpiece model. (Koto's restocks usually take quite a bit longer than Bandai i.e. multiple years even for popular kits, but last fall they announced that they were going to be accelerating reprints of all of their AC kits to match increased demand in the last few years (and teased four brand-new kits), so it's 100% going to be back in stock sooner than later, maybe even within the year).
