Forgeworld is fucking shit and here's why, you just pop a squat right there and let me break it down for you:
Forgeworld is over priced garbage trash and has 0 playtesting as opposed to 40k where the guys in the studio tell upper management that "yeah we play tested it, it's great" nobz in a naut
Take a look at the image I posted there, look at those numbers, those are active warhammer 40k products for forgeworld, take a look at the numbers excluding astra militarum (imperial guard) and tell me what you see.
I'll tell you what you see: SPACE MARINES 277 + (numbers for yiffs and shit), TAU 38, ELDAR 29
There's also a ton of CSM but we'll get back to that in a moment
NOW, lets take a look at what's going on here, the unarguably BEST codices (sm, eldar, tau, I don't care what order you put them in) have HUGE presence on forgeworld, so all the best codices just get better. They get more options, more toys, and these are for codexes which really don't need more options, or more toys.
SECONDLY, you say that forgeworld is more accessible but that is straight up a lie.
Forgeworld is only sold and shipped out of the UK by one company. And it's HELLA EXPENSIVE, now I'm all find and dandy for telling poorfags to fuck off but when you have models which are $200++ for a SINGLE MODEL well you can fuck right off then. I've owned cars that I didn't spend that much money on.
NOW, CHAOS, you might say "hurr durr chaos has presence but that's not op" and I'm here to say FUCK YOU FUCK THAT YOU'RE RETARDED. Most of the "chaos" forgeworld shit is 30k shit which is only legal in 40k as loyalist options a la angels of death, which guess what, loyalists don't need all that fucking shit, and before you say dreadclaw I say fuck you 62 pounds plus shipping for a drop pod which eats your overcosted marines.
