When it comes to Christmas, I find it a relief not to have to deal with the tree, the ornaments, all the decorating, anticipation about gifts, etc. Candles are a hassle-free alternative to the literal mess that accompanies the holiday. I'm reminded of these things when I visit my family members during the holidays - all this hassle, all this build-up and then, BAM, it's over. The only thing about the holidays that I miss are the traditional foods that I grew up with, but it's really not difficult at all to incorporate that into my Chanuka celebration. I spend Christmas with my family and exchange gifts, but I truly feel that this is THEIR celebration and not mine. I'm not pro-Christmas, but I'm not anti-Christmas either - just like I'm not pro- or anti-Chinese New Year, Eid al-Adha or any other celebration by an ethnic/religious group. Other people have their customs and that's great, but I have my customs and I choose to embrace them.
When I was a child and Christian, I loved Christmas, but now that I'm an adult and Jewish, those memories feel like they come from a different lifetime and were experienced by somebody else. I find that engrossing myself in Judaism by celebrating the holidays as best I can and making Tefilla, Teshuva and Tora study something I engage in every day doesn't leave me with much of a hole that needs to be filled when it comes to the holidays. Truth be told, I identify so strongly as a Jew that I sometimes forget that I'm a convert and led a completely different life up until just a couple years ago!
