Is it easier for speakers of SOV languages to learn SOV/VSO syntax or vice versa?
I've been reading about constructed languages recently, specifically the ones intended to be easy to learn such as Esperanto and Ido or trivial to learn but not very expressive such as Toki Pona. These languages or vaguely-language-like-things are basically head initial and have SVO as their dominant word order. I'm curious as to whether this is the "best" choice if the goal is to be as friendly as possible to L2 learners.
OV and VO languages are approximately equally common, although things might be different if we counted languages by number of speakers.
So, I'm curious which order is easier to learn for native speakers of languages using the other order... or if perhaps word order is totally insignificant when it comes to L2 acquisition and ease or difficulty is dominated by other factors.
So far, I've seen a couple of works about L2 acquisition of specific features in specific languages by English speakers and some theoretical things such as this paper that seek to explain the presence of case-marking in SOV languages.
