Avantgarde or Tonian?

Hello, I am relatively new to the SET world. But I was thinking to match my Berning Siegfried (the 811-10 version, 10WPC, OTL) with either a pair of Avantgarde Unos or a pair of Tonian Classic 12.1. Has anyone had direct experiences with both of them? I know they're both good but I was wondering if anyone had first-hand experience of pros and cons. Thanks.
