The Helvetica typeface is delicious. All weights/fonts appear with an unrivaled (almost) aesthetic, except for Helvetica Black - It’s clunky, and the kerning is un-maintenance. Univers Black is far superior, but you’ll need a license, and to send a letter appreciation to Adrian Frutiger (despite him recently passing in 2015)
Avoid Arial (my word) and, many will gripe, but avoid Futura - I can’t stand to see this typeface anymore. So sharp and rigid, with it’s obtuse angles - It makes for awkward body type, and it’s bold variations are hideous in my opinion.
Many love it. Don’t get me wrong. There was a brief time I did as well. Try Trebuchet as a replacement. The angles are more acute, It’s better kerned, Bold is not blasphemous, and if you can stomach the descender in the ‘g’ you’re good to go.
Everyone is using that robo-what-have-you typeface these days. I must say, It’s decent.
