I find the Dice tower useful for things like active stealth, investigation, perception and insight checks. So you don't get things like "Oh I just rolled a 1 on my perception check - I'm sure nothing is here but maybe someone should take another look..."

Like shown in OotS here: https://www.giantitp.com/comics/oots0003.html

I do favor passive checks but sometimes my players do want to make active checks.
