192 ppq is very worthwhile, it's a fine resolution
esp in DAW, when you can zoom waaay far in and shift recorded tracks or single notes in finer increments
more interesting thoughts: TRIM is actually the finest resolution there is
you're dealing with a resolution of 44100 in TRIM
don't shy from changing start points along with your note shifting and swing application
sometimes holding on to a little bit of silence before hi hats and snares is a really good idea for this purpose, because you can drop the actual transient in between ticks this way even though the note itself was recorded in 96/192 ppq
