Topic: UFX+ - UFX2 : which one with iMac 2018 5k

Hi guys & ladies, 1st of all, Hi everyone, i'm new to the forum, i've been using rme interfaces for ages & it's just rock solid products. Great job rme. Now, is there a real perf improvement between the UFX+ & the UFX2 ... i was wondering if the ufx+ worth the invest. i bought the ufx2 few month ago i & just want to know if there is a real speed improvement with the thunderbolt connectivity. Do you think it worth the swap ? I'm not talking I/0, converters, Madi etc etc, just the overall perf of the ufx+ over the ufx2. Thanks for your time & sorry if it's been asked before, been browsing trough the forum, i couldn't find an answer.
