Disregarding the folks currently in training (they seem to show up as IAH), looking at the bottom of the list EWR seems to be the predominant junior base with a sprinkling of CLE, and a few ORD. So for the time being it looks like you can pick and choose, unless you want IAH. I would expect a lot of movement this year, so I'm sure especially with vacancies in IAH caused by CPP movement, even IAH would be attainable within a few months after IOE. Current junior FO in IAH is an April 2018 hire.
