Go with
#1.
Unsolicited website advice: Pattern your website after the logo (
#1) in this case, not the other way around. Your website needs a lot of work, and this logo may be a good starting point.
Also, something about
#2 that no one has pointed out yet is that it is lacking the necessary hyphen to separate 123-freestuff.com from that of 123freestuff.com, which would be a major marketing faux pas. Similaryly,
#3 looks like a hyphen instead of a dot before "com". This may lead some [stupid] people to believe that the other hyphen is a dot also, and they may type 123.freestuff.com. So by process of elimination,
#1 is the best decision (besides its obvious artistic merit).
Hope this helps.
