I have tried several boards but this one is ultimate winner.
I saw it first time on Chris Basement video in combination with Prusa Mk3 and it is supported by Marlin 2.0.
I found BigTreeTech SKR 1.3 for 17 (seventheen) euros on AliExpress, waited for 2 weeks for delivery, previously I had LV8729 (128 step) and DRV8825 (32 step) drivers.
I have combined 8729 for XYZ and 8825 for extruder (First I have tried with A4988 on extruder but it was too loud).
Of course, it is fully compatible with A4988 drivers.

Marlin 2.0 is still in alpha stage but it does hell of a job.
BigTree has Marlin 2.0 firmware version on GitHub, but it is outdated in terms it is not compatible with latest Marlin 2.0 and there is no support for deltas - delta section is completely removed from BigTree config files.
Result was writing from scratch configuration files in latest Marlin 2.0, where Marlin team did great job with example config files for Anycubic kossel, it is a really new dimension in correlated functions and parameters in new config files + PlatformIO IDE is much better than Arduino IDE for work.

Summa summarum:

-100% compatible board with stock parts on AC Linear Plus
-Very fast and precise printing with Arc,Bezier curves and Linear Advance function on
-If you use 32+ steps drivers, you can hear only fans, finally you can print and sleep in same room
-Wide options in menu on M 2.0, you can literally do anything through menu options, i.e. pause, filament change etc works flawlessly
-Price: 17 € board... no comment...

There is only one downside on this board: hotend fan - it is always on when you turn your printer on because there is only one fan output on board and it is used for part cooling.
There is possible workaround to make some outputs on board to be configurable fan output, but I did not care about that.

Here are some results:

In next days I will upload config files and manual how to do it, till then, make some comments :-)
