Seedminer or NTRboot, which to choose to install CFW on 3DS?

Seedminer method and NTRboot method, both supports installing B9S to 3DS for setting up Custom Firmware, like the Luma3ds. So which one is a easier and faster method? What are their differences? Let us give you reply in this post.

Seedminger for 3DS

It's a new way to inject Dsiwarehax to 3DS, made by Gbatemp member Zoogie. This method can install Boot9strap using Dsiware game on 3DS V11.6 and only needs a single 3DS system to work.
There are three different methods of installing boot9strap using DSiWare on 3DS 11.9.0.  Seedminer is the Only one of them works on a non-hacked 3DS, so you are no need to get a hacked source 3DS to do a system transfer. It only requires a PC with a powerful graphics card, a cheap DSiWare game from the eShop. The only problem is it involved many steps and you need to buy a high end graphics card for your PC, otherwise Seedminer method will take all day or some days. The reason it will take so long is Seedminer utilizes your PC's CPU or GPU to brute force a hacked DSiWare Save File to a Stock-unhacked-3DS. If you are relying on CPU its going to take along time, maybe hours, if you have a low end CPU you're gonna be waiting DAYS.

NTRboot for 3DS

NTRboot Method is the way for flashing NTRboothax or Magnethax exploit to your 3DS to hack it totally.
The NTRboothax or Magnethax, a free 3ds exploit to use for running B9S .firm files from bootrom via a compatible flashcard and a magnet! This works on every 3DS on any firmware version. This allows us to have a simple installation of Boot9Strap/CFW to any 3DS, this also enable us to unbrick any 3DS bricked by normal means, all preparations are just a ntrboot flashcart and a maget if our 3DS devices is of a folding style.

Seedminer VS NTRboot, which is better for installing CFW?

	Seedminer	NTRboot
Compatibility	3DS V11.4 to 3DS V11.9	All 3DS Firmware versions
Preperations	A compatible Dsiware game. A PC with powerful graphics card.	A magnet(no need for the original 2DS)  Ntrboot compatible flashcart(R4i gold 3ds plus or Ace3ds X)
Installation	More complicated and it takes longer than NTRboot if your PC with a low end CPU.	Rather simple, it may even takes less than 1 hour for you to boot B9S to install CFW.
Price	$2 for a Dsiware game, but a powerful graphics card costs so high if you don't want to wait for hours or days when using Seemminer method.	$20 more or less for a Flashcart

Conclusion
Apparently, the answer is NTRboot method or the NTRboothax, no the Seedminer for 3DS. It is a full 3ds firmware supported method, take you shorter time to setup and only require a cheap compatible flashcard, even the flashcard can help you play Thousands of NDS games after using for CFW. So if you have a 3ds v11.9 console and want to install CFW with a easy method, take the NTRboot one not Seedminer.
