A minute of unpaid fanboy shilling.
Check out T9A 2.0 rules.
They look really good. Yes, some things LOOK different than WHFB (namely stat line) but that's for ease of reading.
Many things have been well streamlined and I'm glad I don't have to re-read shit 3 times to understand. They are better at wording than GW, that's for sure.
Magic item system was reworked too, but I rather like it. Its more balanced and kinda more fun than old one - and non-magical item options on your characters now matter!
Hordes have been toned down a LOT.
Rear and Flank charges have been buffed, meaning you are rewarded for maneuvering more.
Many armies need less Core (percentages are per-army) and there's no more Rare category, while Lords are mostly 40% now, meaning you can get by with less models.
What is most important, point cost fractions are gone, and shitty point costs of 3 and the like are few and far between.
From modelling point of view, Standard Bearers and Musicians no longer have to stand in the first rank (although they still have priority, in case you want to hide characters behind them).
Armies got some flavour back (not in this version, but in T9A in general) - Aspects and Kindreds back for Wood Elves, Bloodlines for Vampires, Dwarfs can now take those old Doomseekers with chain axes, Skaven get Skryre weapons on Rat Ogre champs, etcetera.
Aside from that, they recently released a supplement for their not!Chaos Warriors, which is basically not!Norsca as seen in TWWH2 (i.e. badass men and northern monsters) - which means more cool fluffy supplements will be coming in the future.
They also promised a not!Dogs of War armybook.
Also also all armybooks and rulebook are updated at the same time, so no more waiting while others get cool toys.
And check out the three "full" armybooks they released. Their fluff is skub, but artworks are gorgeous.
Last but not least, by supporting T9A you encourage 3rd party modellers that fly its banner to stick to FB and not AoS
