A bike that's taller in front (handlebars, stem, head tube) is harder for me to dismount than a drop bar bici or sport moto. A lot more of most people's range of motion in the "splits" comes from hip flexion in the standing leg, than from extension in the leg you're swinging over the saddle, so if your bike's front end keeps you from hinging forward very far at the standing hip, it can be hard to get your leg over in the back.
You always want to turn the handlebars away from the foot you plan to put down - because it induces the bike to lean toward that foot - but if that's an issue, maybe if you turned them even more, they would be less in the way of your head?
Just something that occurred to me. Personally, I'm more likely to get tangled in a step-through frame if I actually try to step through it rather than dismounting the "regular" way. But that's probably just a matter of practice. I do like the convenience of being able to "stand up, coast in, step off" on a step-through - I've never been coordinated enough to do that on a diamond frame.
