There is vastly more difference between high and low quality incense than there is between high and low quality wines or beers.
Like, there's a big difference between a $4 bottle of wine and a $20 bottle, but I'm skeptical about how much actual quality can be detected between a $20 and a $60 bottle. Same with beer: there's a big quality difference between Budweiser and Pilsner Urquell (beyond being different kinds of beer), but less quality difference between Urquell and some $10/bottle craft brew.
