The short version

Only Shottr has a free tier, so it costs nothing to try first.
Each has a real cost: 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.; Shottr it lacks CleanShot X cloud link hosting and self-cleaning desktop features, so teams that share links constantly may find it thinner.
They diverge on capability: Calsense covers Flow-based fault shutdown, Shottr covers Pixel-precise annotation.

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.

Shottr

It lacks CleanShot X cloud link hosting and self-cleaning desktop features, so teams that share links constantly may find it thinner.
Pricing tiers and their exact contents have shifted and are inconsistently reported across sources, making it harder to know exactly what a given tier unlocks before buying.
The free tier periodically prompts to purchase, which some users find naggy over long term daily use.
It is Mac only, offering nothing for a Windows machine in a mixed environment.
Video and GIF recording is more limited than a tool built specifically for that, such as Kap or CleanShot X.
