I just reread the Oblit section in the new Codex.
For a 5pt
increase Oblits have been downgraded..
..from Str5 to Str4
..from T5 to T4
..from a basic save of 2+ to 3+
The body weapons are more of a give and take..
AddPlasma Cannon, MultiMelta, Flamer now Linked
DropAutocannon, Hvy Bolter, Missile Launcher (Frag)
Finally, the big blow IMHO is the move from Elite to Heavy slot.
Still worth it?
I say no..
