Looking for a gbbr

I am interested getting my first gbbr. Realism is important for me but I would also like to start going to local airsoft fields to play again.

What is best gbb for realism, reliability, shooting power and accuracy?

Local field has 1,7 joule limit so would like to have the gun at that area and install npas to lower it if needed.

MWS m4 and URG, and VFC Ak-74M have mostly caught my eye. I like the vfc realism more but mws sound like overall best system. Mws feels too low with 1 J power. What should i upgrade to shoot 1,7 j? Can you shoot well with vfc or easily upgrade it? I have never modified an airsoft gun so would hope to have it as easy as possible to make the gun playable.
