The only format I've had luck with is GeoTIFF.  And Arc seems to have  
trouble with LZW compression (even with the LZW extension), so for  
some space savings, packbits works.  This is what I've used for  
taking SRTM DEMs over to Arc:

r.out.gdal in=dem out=dem.tif cre="COMPRESS=PACKBITS" type=Int16
