Hi Pedro,
my advice is to get the UA-25. Keep in mind that, even if it is 
advertised as 96kHz, you can only record or listen at that sample rate 
(not both). In duplex mode the maximum is 48kHz. The GT8 digital out is 
44.1kHz IIRC, so it is ok.

USB 1 is ok for two channels. You can achieve less latency with PCI 
cards, but this is an issue only if you want to monitor the signal 
processed inside the application. The UA-25 has a direct monitor (0 
latency) that you can use to listen to your processed guitar while 
playing over a track.

UA-25 works OOTB with linux (MIDI works great too).

Hope this helps,
