IMHO the mirror in the first version is more complex and offers more variety. Therefore, I suggest playing that one. I like the second one much less - especially with the building simplifications. I generated the first one many times - never had any issues.
In the second version, roads are on average slightly longer, respawns are slightly bigger in size, so to optimally grab everything requires more brainpower. And accordingly, there are more variations on the subject of take/don't take, which reduces the linearity of the plot and increases the skill factor.
That is, the game scheme and balance are the same, but there are more development options for a match, which is good.
As for never having issues - well, you were just lucky. I tested it myself and others tested it too; the second version generates much more stably, for some players only that one generates at all, while the first version leads to permanent crashes. So going forward, we're focusing on the second one.
No, of course it's your choice what to play, I was just somewhat surprised by your words, nothing more.
