I use ratchet straps.
If I leave them out all year (which, for safety reasons I should not, and am planning to stop) I change the straps before each season. I use 2 and sometimes three points of contacts. Top of stand, bottom of stand, and if adjacent to another bole (I like forked or close trees) I even attach a corner of the stand to the adjacent bole. This prevents the stand from even budging.
I've had chain stands long ago but I only buy stands that have adjustable "backs" to deal with a bit of lean in trees. Very few stands have that option and the ones I use (Lone Wolf and Muddy) use straps.
I don't hunt public land.
