Ortholinear is what you are referring to and it is absolutely worth it to learn. Staggered keyboards don’t make sense anymore - the originally reason keys were staggered was because the bars could not physically overlap - and it is far more natural to type only moving each finger along two axis
With the UHK I am already having difficulty typing directly on my MacBook. With the ortholinear this might only make switching back and forth harder. But it is intriguing.
Or easier. I have switched to column stagger pretty quickly after going to ergo keyboards and I don't have trouble typing on my MacBook. I only dread it now :).
