This is probably more about 'specifically' and 'particularly' as used to expand on the concreteness of a preceding statement. 'Specifically' is more about clarifying the statement with concrete examples in an effort to eliminate misunderstanding. 'Particularly' is to stress the level/degree of applicability of the statement to some exemplary cases.
'certain' can also be used to speak about something that is otherwise considered inappropriate under the circumstance. Couple that with an eye wink to send a stronger signal.
IIRC, Xah Lee in his review specifically mentioned that glove80 are better suited for smaller hands than KA360 as it feels more compact. Having a different pinky column curvature probably also helps. I'd also be interested to know if glove80 is factually more compact (in terms of e.g. key spacing).
Take a look at u/noneagoninf 's reviews here for more first hand experiences.
