I am debating on whether it would be worth it to subscribe to Science and Nature, they are expensive as shit but they seem to have great stuff in them.
Most colleges have an electronic subscription. Check through your library.
I don't think it would be worth it to subscribe to either unless you have money to burn.
If I had the $$ I would subscribe to some woodworking magazines, Popular Mechanics and Pop Science, and a handful of comics.
Edit: I don't subscribe, unless you count library fees, but this is the list that I read from every month:Science, Nature, PNAS, PLoS, ISME, IJSEM, Microbial Ecology, AEM, FEMS, Systematic and Biodiversity, Syst. Appl. Microbiol., Trends in Microbiol, Ann Rev Microbiol., Microbiology NY and UK. - I pick articles related to my field. So, that's about 15-20 per month.
