It's not just smarter it's the only possible solution out of the two. Many people wrongly discuss the premise of basic income in the context of whether it's a better solution for for the job market. I.e. as a better way to solve unemployment fluctuations which in this view are still going up. But the whole point about Basic Income is what we do about there being fewer and fewer jobs that pay a proper salary.
Proponents of the UBI make the generous assumption that recipients will be as careful with money as they (the proponents) are . Choosing between food & housing credits vs. cash, the former has less room for abuse. Its like "I would never use my UBI on alcohol"...well you're not "most people"
Of course, I've seen this evidence in a different context that might be somewhat biased: GiveDirectly[1] provides some credible research and are supported by Effective Altruist organizations like GiveWell[2]. There have also been experiments specific to basic income with similar conclusions[3].
To be fair, none of these studies are remotely bulletproof. Further research would help significantly, as is almost always true in the social sciences. But, in this light, the default position should be that the poor largely wouldn't waste their money—I'd put even shaky studies up against "common sense" any day.

[3]: Unfortunately, I can't find the summary I was thinking of. The Canadian Mincome study[4] is one such experiment and the conclusions, tentative as they may be, are worth a look.
