I kinda like OMGiaDONK, but I'd know who you were either way. I've had similar situations where I didn't like a name I had chosen and had no way to change it other than signing up on another skin (as a side note, I'm finally happy with my current name). But basically I think it comes down to benefits. If all is equal, go with the name you prefer. If you have a considerably larger bankroll or VIP status on one or the other I'd just stick with that one, and maybe switch if you go bust or decide to cash out.
