SBI - Two different Global equity Funds?

[TokyoBoglehead]

So SBI has two very similar low cost global funds.

A SBI・全世界株式インデックス・ファンド

B SBI・V・全世界株式インデックス・ファンド

Although A is cheaper and more established it seems more "suspect"?

It tracks FTSE all cap, via vti, xxus and vt. However, some bloggers mentioned the prospectus has some dodgedy statement that relate to its tracking accuracy?

B is more expensive but purely tracks Vanguard VT.

I ended up going with B, does anyone have any feedback?
