Which service monitoring of site positions in your opinion more comfortable and accurate?

There are many paid programs. Can't make the right choice. I tried to use topvisor, can't compare.
Is there a website of the coupon service, you must:

1. Create/recreate the semantic kernel, to check the position.
2. To delete a large number of indexed pages to see how it is affected.
3. To restart the website on a new engine to see how it affected the positions.
