Is nirvana a mere conscious experience, and if so of what kind?

What is nirvana if it is not just a beatific consciousness free from suffering in all meanings? I want to move away from that and the idea of the perfections (both seem slightly off). So there is meant to be no person to have found its happiness, and soon after nirvana is realised there is no longer even any aggregates to experience its bliss. We agree there is less suffering in the world when a aspirant attains any kind of buddhahood, right? One metaphor is the extinguishment of a lamp, its flame being, I suppose, a kind of burning. Do we look at it pseudo **objectively** (one less thing in pain in samsara), pseudo *subjectively* (the extinction of a particular painful cycle of rebirth), or some mixture of the two (e.g. it belongs to one consciousness but ***a reason for happiness for all***). So could you say it's not just a beatific sense of profound bliss, its the ground of all happiness that does not fool anyone? If so, if that's a fair characterisation (not at all sure it is), do Buddhists define that as a consciousness, and if so with what meaning?
