There are more clients and nasty hacks (*cough* infinite reach) in 1.8 than in 1.9 as far as I know.Actually, there's less hackers on 1.8.
To OP: there's more hacks on 1.9 and the majority of hacks on 1.9 are the same or similar to those on 1.8. The only major difference is kill aura, where it can be adjusted to 1.8 or 1.9 mode.
