Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Koncert

Pricing is not published; the pricing page shows placeholder numbers rather than real rates and directs you to sales, which makes it impossible to compare cost per seat against Orum or Nooks without entering a sales cycle.
Parallel dialling connects representatives so fast that they arrive on a live call with no time to recall prior context, and reviewers report this pushes reps onto a rigid script and degrades conversation quality even as dial volume rises.
Koncert supplies TCPA-supporting features but not legal cover, and parallel and agent-assisted dialling attract regulatory attention in several jurisdictions, so the compliance burden and any liability stay with your organisation.
Selling four dialler products rather than one means the capability you evaluated may not be the one you bought, and switching modes or mixing them across a team frequently involves renegotiating the contract.
The agent-assisted dialler bills for human labour rather than software seats, so its cost scales with call volume rather than headcount and can rise sharply during a campaign push in a way a per-seat budget does not anticipate.
