the best in my opinion is the Valk 3m, I got an angstrom one which is still a good bit cheaper than the Gan 356 X and it has helped me become sub 10. although if you really want one of those three I would go with the gts3m because the x is just as good but more expensive.
You're going to have to define what 'better' means to you. Does it mean faster, more stable, more flexible, lighter, heavier, cheaper, larger, smaller or some other metric?
