I don't know, maybe it's just my thought process... But...

Troll and Iksar both have the 68% experience penalty as it pertains to a shadowknight. They also have regen and Ikky has AC bonus.

Ogre has FRONTAL STUN IMMUNITY (OMG11!!11!!!!!) and a lesser penalty (61%).

For the record, Dark Elf, Erudite and Human SKs "only" suffer a 40% penalty.

If I wanted the best min/max and the best opportunity to solo, I might eat the severe xp penalty and go troll/iksar.

If I wanted to avoid being stunned, and wanted to min/max, ogre.

If I wanted to avoid the severe penalty and liked the look of Dark Elf, Erudite or Human, I'd go with one of them.

In the end, it matters only as much as it matters to you. There are positives to each (though Humans and Erudites are blind, so I'd take that into account) even if it's only in aesthetics.
