I have a cheaper than dog-💩 HF set for construction type stuff (serious wings) and a Freud 208 (very tiny wings).

Love my Freud box joint set  as there are absolutely 0 wings and it produces no tearout which is what I fine most amazing.

I hate shims because they are such a pain to get right but I do respect the ability to get precise cuts when a single pass is require. 
Another thing I hate about the shims is they drop into the arbor threads and get sheared off when I tighten. The center holes just keep getting bigger. Tried tape between the blade and shim to hold them centered but that brings up its own issues.

Was told about magnetic shims but have never tried them.
