I also posted this on the Baby Names board, but I like the sunshine and rainbows of our page better. Which spelling do you prefer? I never even gave Nicolas a thought, it was always going to be Nicholas, but now I've been Googling too much and am having second thoughts.

Nicholas for me too... and I am Katherine too and people do the opposite to me and spell it Kathryn! You can never win.
Nonetheless, it's trying too hard. Stick with Nicholas!
I've got an Irish name, with a few traditional spelling options as well as English spelling options so pretty much no one spells my name right, or pronounces it right here in Asia. It doesn't bother me, because I have a cultural link to the name so it means something, especially while living abroad, but if I didn't I can imagine it being very annoying.
In your case, the traditional and common spelling in English and Western cultures is Nicholas so I'd go with that, unless you have particular links or cultural connections to the Nicolas spelling which may make that worthwhile.
Had to edit because my brain doesn't always work until after I've posted.

I have been surprised to find that some name spellings that I thought were "younique" turned out to be the older spelling. I have a hard time with letting go of the spelling I thought was traditional as the "proper" way.
Five years ago DH and I were joking about what to name our child... he likes traditional names and I don't... so I told him the only way I would name my son Adam is if it was "Atom"...and he fell in love with it because we love science... we thought omg we came up with something soooooo unique... turns out its actually on baby name websites and has climbed in popularity in the past five years... its almost in the top 1,000 in California... so @SkiChic626 as you see no matter what you pick someone out there will hate it and someone out there will totally get why you chose it...
