No issues with the ~6 people I know with S3's and the 1 with an S4.
Where exactly have you been "hearing a lot about this"?
My S3 would charge intermittently. Bought the connector on Ebay for $3 and replace it myself. Took about 15 minutes.
As much as we deride a non-standard format like the Lightning connector, I hate having to try to plug in my phone in the dark (since my wife generally sleeps before me). Her iPhone is way easier (obviously) to plug in.
It's worse since my Note 2 and Nexus 4 have the opposite orientation to my Nexus 7. I sometimes think I must be crushing/breaking the connector every time I guess wrong.
