Flush vs Offset Mount

I’m building out my multiboard with many of the tiles already printed. I’m debating if I should mount it flush or offset to my wall. There seems to be pros and cons to each, but it’s not clear to me what they are. Can someone help me fill in the gaps here?

Offset mount seems like it would have too much flex. However, maybe that’s just a matter of adding offset snaps in the middle of the tiles?

Flush mount seems more sturdy, but I hear that you can’t use certain connectors. What would I be missing out on here that doesn’t have some other kind of work around? Seems like only the pegs and some of the stronger snaps?
