If you like beer, a good NA beer is going to be better than seltzers most of the time. If given the choice between an Athletic NA beer and a La Croix, I will take the Athletic unless it is sweltering hot outside.
I think it's a very personal choice but NA beer just makes me miss normal beer. I'd rather drink seltzer most of the time and have real beer when I feel like drinking. Plus I'm pretty careful about watching my weight and I avoid empty calories where I can.
That is totally fair. Usually if I am in a position to drink NA beer I am out at a bar and just want to have something without alcohol to reduce consumption.
