6-max vs full ring cash games

Do you prefer playing 6-max or full ring cash games, and why? I feel like 6-max is more aggressive but I'm not sure which helps me improve faster.

If you play on GGpoker, full ring is better for rakeback, because when you always go all in with full buy in 200bb, and win that hand you receive GGthanks points (for 100k freeroll every day).

I personally prefer 9-max, because I think, it tends to be a little bit softer with most of the regs being of the tight and predictable type, which is fairly easy to play against. But on small sites with few tables running I will mix it up and play both formats.

I play everything (or have played everything, to be precise).

However, the reason I prefer full ring (9 or 10-handed) is that people often have no clue about playing postflop in multiway pots.

Most of the charts, GTO-lesson, and RTA stuff mostly help with preflop play and HU play postflop.

Live Poker is also mostly not short-handed poker.

Full ring for me, tho i play both. 6max will probably.get you to improve faster as you play more hands and particularly hands in the key positions (BU, SB, BB) more often
