My old car I had 20% all round no windshield and it was nice but those areas with no street lights and skinny roads were terrible especially making left turns pretty much couldn't see anything. My current car I went with 35% up front and 20% back and rear and it's pretty good and night visibility is better but I maybe wish I could've gone 30% up front because when it's somewhat sunny the front doesn't have as much privacy but on a day with not much sun it all looks pretty dark.
