Efest 2104 Purple 2100mah IMR 30A batteries are now available too.
I picked up four of them - so far so good
The Sony VTC 4 IMR/hybrid is the only other 30A battery that I know of with a 2000+ mah capacity.
For the price and availability - I think those are the top two contenders right now. I haven't found any specific tests published on them yet.
All the 1600mah IMR 30A (Efest, Sony VTC3, MNKE, EH, etc) will be obsolete soon.
Same with all the 20amp limited batteries. Although ones such as the Samsung INR 20R and VTC3s are still excellent.
There are a few ICR 30a batteries with higher capacity - but they are hard to find.
I believe LG, Panasonic, Samsung all have some IMR/hybrid 30A 2000+ mah batteries out or coming soon - but they are not as readily available as the new Purple Efest and Sony VTC4.
