I've been testing WoolX's line Lightweight Merino Wool clothing since June. I've been very happy with it. Merino is new to me, so I don't have an extensive direct comparison with merino from other manufacturers, but being someone that had only used synthethic clothing prior to WoolX, I now consider myself a merino convert.
If merino fits your budget, I highly recommend giving WoolX a try!
I agree with the merino, I converted a couple years ago and wear the t-shirts for multi-day hiking all the time. I have a no-name and one from Icebreaker, plus some Stoic boxer briefs which are pretty amazing themselves. Makes your pack lighter when you don't have to bring more clothes to change into.
