Best Note 5 Model for modding?

hi fellow XDA peeps,
Please dont bash me... i did some research but still need a bit of advice....

I am interested in purchasing a Note 5, can someone tell me which version/model of the Note 5 is the best for modding and would most likely be the one with lots of custom roms?
I know it might be a bit early to say this but, I'm hoping that you guys can still give me some advice. I did some research and saw that there is a custom rom or two out right now, especially here on XDA but, i noticed this is specifically for the N920 I/C/G. : http://forum.xda-developers.com/note...om-l1-t3195076

Also, I read that the T-Mobile version comes with an unlocked bootloader. Does the other models come with unlocked bootloader as well?
I would greatly appreciate your help guys and any other advice concerning Note 5 versions/models, modding, custom roms, unlocked/unlocking bootloaders is most welcomed.

1) best version/model for modding and most likely most custom roms?
2) which version/model comes with unlocked bootloader/s?

Many thanks in advance,
Ronald
