Which is the Best Flashcart for 3DS Roms?

We are paying attention to the 3DS flashcarts for a long time. As we known, Gateway 3ds is the first one can run 3DS roms and NAND-emulate.
Then R4i Gold 3DS Deluxe and 3DSLink Released with cheaper price.
At the end, MT-Card 3DS came out, which was the first and only 3ds flash card can support multi 3ds roms in one Micro sd card, it really has many powerful functions for players,  and just now , we noticed MT-Card official reseller Digimartz.com news: MT-Card V1.1 firmware & V1.2 Hardware released!  With this update , it can support NAND-emulate, region free,ESHOP,NAND backup, the popular 3ds games are all available(such as Pokemon X/Y , Animal crossing …) . And so far as I known, the V1.2 firmware , which fixed many eshop games (eg: Harmo Knight , Phoenix Wright 5, Super mario bros deluxe) , will be coming soon!
So, till now, MT-Card’s functions and also the great value are the best 3ds flashcart as i known. Even for the OMEGA 2.1 firmware released , the GATEWAY 3DS‘s  multirom function had been extended and become the 2nd to support 3DS Multi-ROM.
