Where each one falls short

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

Calsense

It is a North American product with a narrow dealer network, so agencies outside the United States have effectively no route to buy or support it.
Install cost is high relative to commercial irrigation controllers because flow sensing, master valves and proper wiring are part of the design rather than optional extras.
The interface and workflows are built for irrigation technicians, not casual users, so a small grounds team without a dedicated irrigation specialist will underuse most of what they paid for.
Public sector focus means procurement paperwork, bid specifications and cooperative contract vehicles are part of the process, which lengthens purchase timelines regardless of budget availability.
No pricing is published, and the no-subscription claim is conditional on the communication model chosen, so the total cost cannot be established without a specific quote and a careful read of which model applies.

Hazel

There is no free tier, only a 14-day trial, so the full 42 dollar cost is a real barrier for a casual user just wanting one simple rule.
Rules are entirely hand-built, so the tool provides no value until a user invests time writing and testing conditions.
A misconfigured rule can silently move, rename or delete the wrong files, and mistakes are only obvious after the fact unless tested carefully first.
It is Mac only, so it does nothing for a Windows machine sharing the same file workflow.
It focuses purely on file automation, so a user also wanting window management, clipboard history or gesture control needs entirely separate tools.
