I just installed ubuntu 12.04 and I began using Gwibber for my accounts of twitter and facebook, but it's so slow.
If I had to make a "top 5", it would be, from the best to the worst (not tested Pino) :
- Hotot (fast and the most complete).
- Polly (nice and promising client). It is formerly known as "Schizobird".
- Choqok (a little worse than Polly).
- Gwibber (too much basic).
- Turpial (one of the worst Twitter clients I have ever seen).
But the best thing to do is testing them all and making your own opinion about this.
You might be interested in Choqok.
sudo apt-get install choqok
