In terms of quality or just overall performance? I've bounced around between Buffer and Later, and no tool is perfect. When I start to get comfortable, an error rears its head. Posting straight from the phone is more error-proof, but it's a time-sink. I've seen Polish and verified work from buffer still get a snap and mess up the formatting or not post an image, but it's extremely rare but does happen. For me, it depends on the output of the work. The third-party integration is worth the low fail rate and overall dashboard to not have to post from the phone
