Which Tier 6 Light Tank is Better?

Tell me if I missed one pls.

This one is actually a tough call for me, as I've only owned the T37 and the VK 28.01.  In my mind, the 59-16 and type 64 are right up there close to the one I voted for, the T37.  Here's a link comparing those 3:

As you can see, the T37 has significantly better hit points, aim time, penetration and gun depression than the other two.  Of course that's just a comparison of only 3 of the 6 tanks in question with a specific gun selected.  The most drastic difference to me that stands out and puts the T37 ahead of the competition is the penetration of its gun over the others. A successful engagement often comes down to simply whether or not you can pen the target at the given angle in that particular situation/shooting opportunity/time window. Granted, that isn't the only factor. But in my opinion that makes it my first choice for use in strongholds.

This survey is for me (and anybody else) to figure out which tank may be worth to grind for. Just saying ^_^

The t21 just sucks.

I vote Type 64
