Push pull OPTs have a small gap to allow for current imbalance. On EI cores, it also allows for the winding imbalance that is inherent to the way they are made.
The gapless ones are for places where you can guarantee no current, or at least no imbalance - such as parafeed. The small gap will actually linearize them a bit, and will make them usable for other applications. So if these are for experimentation I would get the standard version.
The LL1620's are probably what you want. At 300H of primary inductance, they will be fine for parafeed duty.
