it depends on what kind of game style you prefer. if you like priboi, there is no other similar mod out there.
if you like the run-and-gun style mods, then there is many modpacks, such as ol mod, smp mod, abc mod. i dont know any other usable mods at the moment.
if you want to look back and try these modpack's mother (which they were built ontop) you can try amk. (but i guess you already played it
)
also there is a soljanka mod, which is built on top amk, but it also contains kostya_v-s mappack. so it brings something "new" to the zone.
thats all i know... not much, isnt it?
edit: there are some mods which don't touch the vanilla game, only adds graphics mods, but im not sure if they are needed in your case...
