Which is the Best Flashcarts for 3DS Roms? MT-Card, Gateway 3DS or R4i Gold Deluxe?

I'm attention the 3ds flashcarts for a long time.

Gateway 3ds is the first one can run 3DS roms and NAND-emulate;

Then R4i Gold 3DS Deluxe, 3DSLink Released, with cheaper price;

At the end, MT-Card 3DS come out, which is the first and only 3ds flash cards can support multi 3ds roms in one memory card, it is really a great function,
and just now, noticed MT-Card official reseller 4CoolDay.com news,
MT-Card V1.1 firmware released,
which can support NAND-emulate, region free,ESHOP,NAND backup.

So, till now, MT-Card's functions are the best as i know.

By the way, is there a good function Gateway 3DS has but MT-Card hasn't?

 

mt card

 

i like gateway 3ds better, more expensive but team is strong, expecting their 2.0 firmware!

 

someone says the modchip of gateway 3ds can't support multi roms.
If it is true, i think MT card is the best.

 

there are many flashcart sellers, they usually recommend the R4i gold 3ds delux ediiton to me.because it comes from the r4i gold 3ds official team i bought one for a time , but it didnt work well ,bad quality. so recently i also bought a gateway 3ds,more expensive but much more reliable, from another site, fast shipping, works great,

 

For DS Games, the R4i gold 3DS will be great,
For 3DS roms, MT-Card 3DS and Gateway 3DS will better.

But Gateway 3DS still can't support multi roms,
and don't know when it will become true.
