Hmm, interesting. It looks like cooling issues to me. The PLA was ran at a significantly lower temp I assume and probably with forced cooling?

I'd say the ABS needs more time between layers to cool. It is a different plastic all together so it is hard to compare. Usually when something like that happens try printing 2 pieces at once on opposite sides of the build plate. Possibly need to drop the temp of the ABS to 220 or so. Keep build plate at 90c.
