I flew them in Envoy (Biz) and sat in the Y seat for a few mins to try it out
seat wise in biz or coach Id take US over CO any day of the week providing you dont need the afternoon flight or morning flight back from TLV.US ha sbut 1 flight a day it arrives into TLV @ 3:15pm the mylar to CO is I usually flew the 84 there and 85 back so you can fly say on Thurs afternoon and have no problems with Shabbos which cant be done with US or COs night flight
same back you can take COs Fri morn flight (non-winter time) and you get in at 4:30pm
If Service is important to you having an FA stopping by every few mins then you wont want US, I flew TLV-PHL so I cant comment on the food out of PHL but I thought CO gave alittle more out of TLV but since the food is from the same place it STINKS anyway so maybe less of it is better
In biz on US its more of a ^ in the middle section so you get more privacy while CO is // and no privacy. didnt take note of USs side sections as I usually go for the middle, on CO its all // or (left side setup is a backwards slash dont have it on my NB)
If I had a choice and the timing of the flight wasnt important Id go with US Everytime! I found it to be that much better even over COs new seats in BF, in coach not even close US all the way = leather seats with some support.CO = a plank of wood with commerical carpeting covering it
