Based on your criteria, I'd say the Big Bang Pegasis DX Set is your best choice. Reasons:
It does indeed come with a BB-10 stadium
A string launcher is included (generally considered better than Rev Up launchers simply based on consistency, which rev up launchers have a hard time delivering)
None of the sets really come with Beyblades that are particularly up to speed with the current meta game, however the Big Bang Pegasis DX Set includes some parts that are useful or top tier - namely the extra tracks and RF. XF also some some niche uses.
Reasons over the other sets:
Galaxy Pegasis DX set has most of the Big Bang Pegasis DX set contents, however other than R2F, Galaxy Pegasis is not very worthwhile.
Fang Leone is overall outclassed and Big Bang Pegasis on its own is not particularly useful. They are nice recolors though.
The BB32 is nice in that it comes with 2 string launchers and a stadium (BB-10), however Dark Wolf is thoroughly useless and Storm Pegasis only has RF (top-tier attack piece) however this is included in the Big Bang Pegasis DX set.
Edit: somehow I missed that you did NOT include the BB-107 Big Bang Pegasis DX Set in your post, however I still think it would be your most viable option since most of these sets float around the same price range.
