1.b3 or 1.g3?

Plus the main line after b3 the most popular move is e5 and not d5 (Modern Variation)
1. b3 d5 (Classical Variation)

Well when you push a center pawn ( d or e ) first, you'll control the center which is crucial as of chess principles rather than pushing a flank pawn. But flanks are good in a way too.

Good point but I can do a break with my pieces ready like d4 or e4

It's a chess principle but who cares!

Fischer played a great game in this line lichess.org/zkKLicVo/black#132 .
g3 often transpose into other opening structures like the Catalan, English or the King's Indian attack. b3 is a opening by itself cause it creates new plans for white
i say that 1.b3 could be more flexible because it can transpose into many openings such as larsen, colle,queens gambit etc but 1.g3 can only transpose into modern as white if black plays 1.e5(forget about the idea of double fianchetto because it can be achieved with both the moves)
