I have been using a mix of both. As Saelorn says, sometimes the activity should allow characters to succeed where they normally couldn't. This is where the helping rules really break down, in particular. If you can't move that boulder, a buddy helping will make no difference.
Advantage/disadvantage works great for other situations. Buy everyone a round of drinks at the tavern, get advantage on asking for information. Clothes looking a little unfashionable? Disadvantage on talking your way into that party.
So, I mix and match numerical adjustments with advantage/disadvantage. It's easy to do both, and I believe is is a simple adjustment which makes play better.
