Channels with final states photons at LHC

Dear Calchep authors,

May I ask is it not preferable to detect a particle at the LHC with final states of photons, that when I read
in many papers I find for example for a particle beyond SM like an octet scalars if they could decay
into jets and photons+jets ( S^+ -> S^- A -> t b A), only jets channels take a concern, so do jets or
leptons detection has advantages than photons siganls ?

Thanks,
Safinaz
