This is a kind of Ford vs Chevy position but I personally would NOT use any Atlas electrical circuit controller on my panel. The installed schematic is very tempting but in my experience, there is a variable rate of dependability.
I have been at this game for decades, and yes the failure rate is not over whelming, but the failures that have happened have been a determining factor in never using them again.
Another feature to consider, terminal strips. They come in many different multiples of posts. Some brands have slide on sets of posts so you can make your own quantity count .
All soldered connections to track or Tortoise or whatever simply drop down to a terminal strip or direct t o a relay. This way any component can be removed with a simple unscrewing of just the wire drops involved.
Soldered connections are your friend.
This is how tortoise switch machines can be prepped and attached. Example for a 2 rail double cross over.
Sometimes I use the EDAC 306-008-521-101 eight pin slip on connectors. Very convenient but some folks say they can have less than secure connection.
I use 9 wire conductor 18 ga HVAC control wire.
